- How do surviving children heal from unimaginable betrayal?
- What physical clues finally shatter a carefully constructed lie?
1. Emergency Room Nightmare
Medical staff at McKenzie-Willamette Hospital faced an unprecedented emergency when three children with severe gunshot wounds were brought in late at night.
The Late-Night Emergency Call
On May 19, 1983, at 10:40 P.M., an employee notified the Springfield Police Department about gunshot victims arriving at the hospital. Officer Rich Charboneau arrived at the hospital eight minutes after the initial call at 10:48 P.M. Dr. John Mackey and nurses Shelby Day and Rosie Martin encountered a horrific scene at the cramped emergency room. They worked frantically to save the children despite obsolete facilities and heavy blood loss.
Catastrophic Injuries
The three young victims suffered catastrophic chest wounds from close-range gunshots, resulting in one fatality and two severe survivable injuries. Cheryl was dead upon arrival with bullet wounds in her back. Her sister sustained multiple through-and-through chest wounds that caused massive hemorrhaging and heart stoppage before surgeons revived her. Their toddler brother had a near-contact bullet wound near his spine threatening his mobility.
Dr. Steve Wilhite performed an exploratory thoracotomy on the surviving girl and removed 300 ccs of bright red blood from her collapsed lung.
- T-6 and T-7 marked the spinal area where the bullet slammed into the young boy's back.
- Life-Pak leads monitored the fragile vital signs of the children during frantic medical interventions.
Diane's Detached Arrival
Diane Downs arrived at the hospital in a state of calm shock after her children were shot, presenting an unusual mix of physical attractiveness and emotional detachment. Hospital staff noted Diane's bizarrely flat expression and hypnotic, empty eyes while she insisted a gunman had targeted her and her children on Old Mohawk Road. Medical personnel also treated her for a non-life-threatening wound on her left arm.
Judy Patterson at McKenzie-Willamette Hospital comforted Diane, who repeatedly demanded to call her parents while showing little visible grief over her children. You watch the unfolding tragedy as medical workers confront the devastating aftermath of a Saturday Night Special during the Morning Watch shift.
2. The Investigation Begins
Detectives launched a massive search along Old Mohawk Road while growing suspicious of Diane's continuous, robotic monologues and calm demeanor.
Lane County Detectives were called to report to the hospital at 11:15 P.M. Law enforcement launched a massive search along Old Mohawk Road for an armed suspect while beginning to doubt the logistical details of Diane's narrative.
Searching Old Mohawk Road
Detectives and deputies scoured the dark, isolated stretch of road where Diane claimed the attack happened. They deployed tracking dogs and checked for witnesses or a yellow car, but found no trace of an assailant.
Sergeant Rob Rutherford drove Diane and her father Wes back to the supposed crime scene on Old Mohawk Road, where Diane mentioned a brass unicorn she had recently bought.
Interrogating the Mother
During questioning by detectives, Diane Downs spoke continuously and robotically, offering excessive details while maintaining an emotionless facade. You watch as investigators listen to an endless stream of words.
Detectives Dick Tracy and Doug Welch noted that Diane's words poured out like a flood. She displayed high intelligence and rapid recall of dates and vehicle details while remaining emotionally detached from her daughter's death.
Diane explained her IQ level to detectives and gave precise birthdates for her children while being interviewed in the hospital treatment room. She claimed to inhabit level 7 out of eight levels of intelligence.
Unpacking the Q Street Duplex
A search of Diane's sparse townhouse revealed an unpacked living space, an incriminating engraved statuette, and a hidden rifle. You see the bleak environment left behind by the family.
Investigators found almost no furniture or food in the Q Street duplex. They recovered a .22 rifle from the closet and a brass unicorn statuette engraved with the names of her children and the date May 13, 1983.
Detectives Dick Tracy and Doug Welch inspected the empty refrigerator at 1352 Q Street in Springfield and found the engraved unicorn statuette on top of the television console.
3. Forensic Clues and Prosecutor Bond
Assistant District Attorney Fred Hugi bonded fiercely with the surviving children while criminalists processed physical evidence from the vehicle and crime scene. You see how legal duty and intense personal grief intertwined during the investigation.
Hugi and the Children
Fred Hugi formed an immediate and fierce emotional attachment to the surviving Downs children upon seeing them in the intensive care unit. Despite being a private man who typically avoided children to focus on his career, Hugi wept upon locking eyes with Christie Downs in the hospital and silently resolved to protect them.
When Hugi visited Christie and Danny at McKenzie-Willamette Hospital, investigator Paul Alton witnessed him crying and subsequently adopting the role of their guardian. Hugi arrived at the hospital at 10:05 on May 20, 1983, and his life changed permanently that night.
Locard's Exchange Principle
Forensic science relies on Locard's exchange principle, which states that perpetrators always leave microscopic evidence at a crime scene and take traces away. Modern criminalists apply sophisticated technology to analyze invisible clues such as blood spatter patterns, gunpowder particles, and fiber transfers.
- Locard's principle has guided forensic investigations for seventy-five years.
- Experts analyze blood spatter pattern interpretation to reconstruct shootings.
- Criminalist III Jim Pex and Jon Peckels examined the physical evidence.
Oregon State Police criminalist Jim Pex and Jon Peckels processed the interior and exterior of Diane Downs's car, discovering physical evidence including bullets, casings, and blood. They recorded an odometer reading of 5,948 miles on the Downs vehicle.
Vehicle Ballistics
Forensic examination of the victim's vehicle revealed specific ballistic evidence and a lack of gunpowder residue on the driver's side. Criminalists found blood pools, bullet fragments, and gunpowder particles on every quadrant of the vehicle except the driver's seat, supporting specific interpretations of the shooting positions.
Jim Pex and Jon Peckels found spent .22 caliber casings head-stamped U in the blood on the backseat and recovered a .22 lead bullet from beneath the carpet. The recovered lead bullet weighed .39 grains, while the bullet from Cheryl's autopsy weighed 38 grains.
4. Unraveling the Alibi
Investigators dismantled the narrative of a bushy-haired stranger while uncovering Diane's traumatic childhood and history of unstable relationships.
The Bushy-Haired Stranger
Diane claimed a shaggy-haired man flagged down her car and shot her children. Investigators note that suspects frequently invent a mysterious stranger to deflect guilt because such a person can never be produced or disproven in court.
Law enforcement relies on the concept of hinky feelings. These are subtle inconsistencies that signal a narrative does not make logical sense. Paul Alton pointed out the impossibility of a stranger accurately intercepting Diane's vehicle on an unscripted, winding detour like Old Mohawk Road.
Detectives analyzed the physical layout of the journey. The shooter's alleged actions raised major doubts:
- knowing her exact route;
- ignoring the adult driver;
- shooting sleeping children.
Diane Downs showed remarkable calm during her hospital recovery. Fred Hugi observed that she displayed no normal signs of maternal grief or distress. She eventually remarked to him that she was growing stronger and would beat the accusations.
Detectives noted that Diane acted remarkably unaffected. One observer remarked that her attitude was totally inappropriate for a grieving mother. She missed the initial arrest window after the crime at the forty-eight-hour cut-off point. May 23 marked the date Diane was released from the hospital.
Childhood Isolation and Abuse
Diane Downs experienced severe childhood isolation and paternal abuse. These factors shaped her deeply fractured self-image and coping mechanisms.
Diane was born in 1955 as one of five children in the Frederickson family. She possessed a full-scale IQ score of 125 on the Wechsler Intelligence Scale.
Diane recalled retreating into a mental state of blanking out to escape the trauma of sexual abuse by her father, Wes Frederickson. She received little emotional support from her young mother, Willadene.
Diane cut her wrist when she was thirteen and later attempted to jump from a moving car during a terrifying ride with her father.
Escape Through Marriage
5. Psychology of Pregnancies and Obsessions
Diane used pregnancy and surrogacy to fill internal emotional voids, committing severe child neglect when her offspring failed to provide unconditional love.
Pregnancy as a Cure for Emptiness
When your adult relationships fail, you might search for a reliable source of affection. Diane Downs used pregnancy and childbearing as her primary psychological mechanism to feel whole, loved, and needed.
Feeling rejected by her husband Steve and haunted by childhood trauma, Diane decided to grow her own source of pure love by having babies. She treated the male contribution merely as a source of viable semen while she viewed herself as the sole creator of life.
When her marriage to Steve deteriorated and her Air Force career failed, she immediately conceived children, treating each pregnancy as a near immaculate conception.
The Trauma of Abortion
An abortion performed in 1975 later triggered intense psychological guilt. This procedure turned a lost fetus into an obsession that Diane sought to replace through subsequent pregnancies.
Initially viewing a six-week fetus as mere slime, Diane later saw a right-to-life display showing a developed fetus and became convinced she had committed murder. She named the lost child Carrie and attempted to recreate her.
Diane underwent an abortion in 1975, but two years later at an Arizona fair, she saw a right-to-life booth display that convinced her a fetus was a human being. This encounter led her to obsess over replacing the child she called Carrie.
Surrogate Parenting Pursuit and Neglect
Diane sought to become a surrogate mother both to escape her mediocre life and to earn a substantial financial payout. Psychological testing during the surrogate screening process revealed profound ego deficits and histrionic traits, though she ultimately passed the evaluations.
Evaluators noted that Diane exhibited a superficial affect, poor behavioral controls, and a histrionic personality disorder. These evaluations suggested she used pregnancy to escape personal inadequacy, yet she was cleared by a later psychiatrist.
Diane wrote to a surrogate parenting clinic in Kentucky after seeing an episode of the Donahue Show. She carefully omitted her true marital instability and psychological turbulence in her application to Surrogate Parenting Associates, Inc., drawn by the prospect of receiving 10000 dollars upon delivery.
During her screening in Kentucky and later in Phoenix, Diane underwent 10 standard tests, including the WAIS, Rorschach, and the Minnesota Multiphasic Personality Inventory (MMPI). These exams exposed her deep-seated feelings of inadequacy and ability to shut off emotions at will during a session lasting 1 hour and a half.
Diane's frustration with her children failing to provide unconditional love resulted in severe verbal and physical abuse, as well as dangerous neglect. You see how she viewed her children as burdensome when they failed to make her happy, screaming at them and pulling their hair.
Five-year-old Cheryl told a neighbor's housemate that she wanted to shoot herself because her mother told her she was bad. Older sister Christie frequently had to care for her siblings during Diane's prolonged absences, managing household responsibilities by 6 years old while 15-month-old Danny was left with sitters or alone.
6. The Arizona Affair and Blood Spatter
Detectives uncovered Diane's obsessive romance with Lew Lewiston and discovered high-velocity back-spatter blood patterns that shattered her roadside ambush story.
Diane viewed her surrogate pregnancy as a source of immense emotional stability, status, and happiness. This feeling contrasted sharply with her neglectful treatment of her own children. While carrying a surrogate child for unknown parents through an agency, Diane felt validated and important. She received a 10000 dollar fee for the surrogate baby and met the legal time in Kentucky required to finalize parental rights of 5 days.
Neighbors like Mary Ward and Dan Sullivan frequently had to feed Cheryl because she was hungry and neglected. Cheryl once nearly stepped in front of a car because nobody cared.
The Lewiston Journal and Interviews
Investigators analyzing the aftermath of the shootings uncovered a revealing spiral journal written by Diane. The document detailed her deep infatuation and subsequent agony over her breakup with Lew Lewiston. Oregon detectives reviewed Diane's unsent letters in her personal diary, which tracked her obsessive fixation on Lew. The letters provided investigators with a clear psychological motive and pointed directly toward her turbulent romantic life as a key element of the case.
Doug Welch and Paul Alton flew to Chandler to interview Lew and Nora Lewiston. Nora Lewiston displayed a remarkable memory for dates and timeline details, corroborating the exact progression of the affair. Nora recounted how Diane conspicuously sat across from them at a company picnic and interrogated her children about loving their mother.
High-Velocity Back-Spatter
Forensic testing on Diane's vehicle revealed critical high-velocity back-spatter blood patterns, casting immediate doubt on her fabricated account of a roadside ambush. Crime lab analysts examined the red Nissan and identified human blood flecks on the rocker panel below the passenger door. Experts recognized this specific pattern as high-velocity back-spatter, indicating that a shooting occurred at very close range near the ground.
Jim Pex rolled the red Nissan into the sunlight and discovered the dark red mist patterns on the vehicle's exterior.
7. Motive and Weapon Evidence
Investigators confirmed Lew's absolute rejection of Diane and matched tool marks from her closet rifle to cartridges found at the river crime scene.
Obsessive Affaire Mechanism
Diane channeled immense energy and manipulation into trapping her married lover, Lew Lewiston. You see that she relied on constant communication, gifts, and emotional pressure to force Lew to leave his wife Nora. Lew showed recurring hesitations and refused to become a father to her children. Diane clung to minor tokens and isolated promises as proof of permanent commitment.
Diane gave Lew her gold chain and persuaded him to get a red rose tattoo on his arm. She viewed these as unbreakable signs that he was bound to her forever.
Definitive Breakup
Lew Lewiston definitively ended the affair and resolved to stay with his wife. Once Diane departed for Oregon, Lew experienced total relief. He refused her phone calls, returned her money via a check, and rejected her final surprise visit in Chandler where she attempted to return his gold chain.
On April 28, Diane drove up behind Lew on his mail route using a borrowed truck and tried to stage a dramatic romantic reunion. Lew spoke only twenty words to confirm it was completely over. Investigators recognized that Diane had wagered everything on Lew following her to Oregon, and her grand gamble had completely failed. Lew expressed profound fear that if Diane escaped conviction, she would return to harm him and his wife Nora.
Ballistics Match and Tool Marks
Ballistics tests linked cartridges found in Diane's home to the missing murder weapon.
Experts Chuck Vaughn and Jim Pex discovered that unfired cartridges in Diane's closet rifle had extractor and ejector tool marks mechanically identical to casings found at the river crime scene.
Vaughn and Pex matched the tool marks left by the receiver of the missing .22 Ruger on cartridges found in Diane's bedroom rifle clip.
8. Legal Pressure and Child Testimony
While Fred Hugi weighed the timing of an arrest against the speedy trial rule, young Christie slowly recovered and processed her traumatic memories.
Prosecutorial Dilemma
Fred Hugi faced intense anger from police and investigators who wanted to arrest Diane immediately. However, Hugi knew that circumstantial evidence alone might not convince a jury. Oregon law required a speedy trial within three months after an arrest.
This strict deadline presented a severe obstacle. The traumatized and speech-impaired Christie would not be ready to testify within that window.
Fred Hugi held daily meetings that eventually disintegrated as cops grew frustrated with his refusal to rush into filing murder charges against Diane without foolproof evidence. These sessions lasted for two weeks before the police pressure boiled over. You can see how delicate the timing was when a single missing witness ruins an entire case.
Eyewitness Inman Testimony
Joseph Inman and his family saw Diane's red Nissan traveling at an abnormally slow speed on Old Mohawk Road right after the shooting. Despite open windows and a two-minute crawl behind the car, Inman heard no cries for help. This observation directly contradicted Diane's claims of racing frantically to the hospital.
Joseph Inman followed Diane's new red Nissan on Old Mohawk Road, noting it crawled at five to seven miles an hour just eight tenths of a mile west of the probable shooting site.
The journey covered a total distance of 12.5 miles from Heather Plourd's trailer to the McKenzie-Willamette Hospital.
Christie's Trauma Recovery
Child victims of severe trauma often repress details and struggle with verbal expression. They require specialized and gentle questioning techniques by professionals.
Paula Krogdahl interviewed the recovering Christie in the hospital using indirect prompts and visual aids like dolls and drawings. These tools helped Christie express memories without inducing panic or feeling at fault.
Paula Krogdahl asked Christie about a jigsaw puzzle and used a red skirt to prompt memories of the red car before slowly uncovering details about the guns and the events in the car. The interview group gathered in Christie's hospital room on June 16 at 11:00 A.M.
Christie was finally released from McKenzie-Willamette Hospital on June 22, 1983, after five weeks of treatment.
Carl Peterson used non-directive counseling to help Christie process her severe trauma at her own pace. This approach allowed her memories to emerge gradually from a mental vault rather than forcing an immediate prosecution-driven narrative. Christie drew pictures of her family, a red Nissan, two guns, and a diagram of Heather Plourd's house for Dr. Peterson while dealing with aphasia.
9. Interrogations and Secret Meetings
Detectives subjected Diane to grueling interrogations while Steve Downs violated custody orders, allowing Diane to hold secret meetings that temporarily derailed Christie's progress.
Doug Welch and Kurt Wuest questioned Diane in a twelve by fifteen room with beige walls and a view of a courtyard. They used audio recording and pressed her to explain illogical timelines, her failure to act during the shooting, and newly claimed memories of a gunman.
Pushed to her emotional limit under intense questioning about how she survived with only an arm wound while her children were shot dead center, Diane shouted that she remembered everything.
Diane stood up and ran out of the Criminal Investigation Division, prompting the detectives to record the exact time of her departure as 17:46.
Secret Meeting Setback
Steve Downs violated court orders by allowing Diane to meet secretly with Christie, which severely damaged the traumatized child's psychological progress in therapy. Steve brought the children to a park and permitted Diane to take Christie alone for hours, during which Diane told her daughter not to talk about the case.
Christie visited her mother and grandparents, played computer games, and was later returned in a somber, closed-off state, causing therapist Carl Peterson's timeline for her testimony to lose validity.
Dr. Peterson had initially estimated a timeline of four to six months for Christie to describe the shooter, and she was nine years old at the time of her birthday in October 1983.
The Pregnancy Sentence Shield
During the December contempt hearing, the revelation of Diane's pregnancy convinced the judge to issue a suspended sentence rather than jail time. At the show cause hearing regarding the violation of visitation orders, defense attorney Jim Jagger announced her pregnancy, which caught reporters and the court by surprise.
Judge Gregory Foote granted a one-year suspended sentence after considering that Diane was two to three months pregnant.
In court, Diane testified that Steve had threatened to take her out if she did not stick to his version of events, while attorney Bill Furtick cross-examined her about the secret meetings.
10. Indictment and Trial Preparations
A secret grand jury handed down felony indictments, prompting extensive legal preparations, witness schools, and the use of forensic dolls.
Pierce Brooks Consulting
Bringing in legendary homicide experts helps police structure complex circumstantial murder cases into visual presentations suitable for juries. Pierce Brooks, an experienced LAPD homicide captain and expert on serial murder, reviewed the Downs case files, drove the routes, and advised the local prosecution team. Drawing on his experience prosecuting the Onion Field case, Brooks stressed the need to graphically display evidence such as bullet angles, tool marks, and blood spatter using physical recreations like a model car and life-size dolls.
Pierce Brooks evaluated the Datsun murder car and listened to Diane's recorded interviews before agreeing with Fred Hugi that Diane possessed guilty knowledge. You find that external experts often spot critical patterns that local investigators miss during long inquiries.
Ray Broderick Dolls Interview
Anatomically correct dolls can help child trauma victims safely demonstrate the mechanics of a crime without verbalizing every detail. DA investigator Ray Broderick used specially crafted dolls corresponding in size to the Downs children to establish rapport with surviving siblings and encourage them to reenact the events of the shooting scene kinesthetically.
When Broderick brought the dolls to the Slavens' house, Christie spontaneously placed them in a couch-car setup and reenacted the shooting by pointing her finger and mimicking the gunfire.
Secret Grand Jury Indictment
A secret grand jury meticulously reviews months of witness testimonies and physical evidence before officially handing down felony indictments. After almost nine months of meetings, the secret grand jury evaluated over two hundred pieces of physical evidence and numerous testimonies from family members, investigators, and experts to determine formal charges against the suspect.
The grand jury heard testimony from fourteen individuals, including Christie, Diane, Steve, and various relatives, before issuing Indictment Number 10-84-01377. You see how patience and thorough documentation build an ironclad foundation for a major criminal trial.
11. The Courtroom Confrontation
Prosecutor Fred Hugi framed the prosecution's case around lust as a motive and read Diane's explicit, manipulative poems and letters to the jury.
Hugi systematically outlined how Diane viewed her children as the sole obstacle to marrying a man who did not want children, reading aloud her graphic writings to establish her crafty intelligence and obsession. The opening statement spanned an expansive 80 pages of transcription while preparing 50 witnesses to back up the prosecution's case.
Hugi read Diane's masturbation poem to the courtroom, causing a profound hush among the elderly and middle-aged gallery while Diane cried softly into her handkerchief.
Christie Testifies
Medical experts testified that surviving victim Christie Downs suffered a stroke affecting speech, but her memory of the event remained intact. Physicians explained the neurological impact of Christie's gunshot wounds and stroke, noting that although her speech was delayed and she searched for words, her feedback loop and comprehension were functioning.
Dr. Bruce Becker explained to the jury through diagrams of the brain that Christie would recognize her own speech errors instantly and attempt to correct them.
Despite deep trauma, physical impairment, and immense fear, 9-year-old Christie Downs took the witness stand 361 days after she clinically died and testified that her mother shot her and her siblings. Christie faced immense psychological pressure and the risk of suppressing her memory, but she courageously testified in front of the judge, a jury of 15 jurors, and 80 spectators, identifying her mother as the shooter while mentioning the song playing on the tape deck.
Christie lifted her paralyzed arm with her left hand, laid it in her lap, and answered Fred Hugi's questions, identifying the song "Hungry Like the Wolf" as playing in the car.
Forensic Doll Reconstruction
Forensic expert Jim Pex used rag dolls and a car mockup to demonstrate the exact positions of the victims and the shooter during the attack. By inserting probes through the wounds of the rag dolls placed inside a mock-up of the Nissan Pulsar, Pex reconstructed the angles of the gunshots, showing close stippling and contact wounds.
Pex demonstrated how the shooter must have leaned into the car to shoot Danny and reached across or around the car to fire a second contact wound into Cheryl, utilizing the Sodium Rhodizonate test, the Greiss test, and back spatter analysis to confirm distance measurements ranging from 6 to 9 inches for Diane's forearm to 9 inches or less from Danny's spine.
12. Verdict, Sentencing, and Aftermath
The jury convicted Diane on all counts, leading to a life sentence with a twenty-five-year minimum and eventual adjustment for the surviving children.
Jury Deliberations and Guilty Verdict
After more than three days of deliberation, the jury found Diane Downs guilty on all charges. You can see how the lengthy trial culminated in a late-night resolution when the facts overcame the defense.
Daniel Bendt, the young engineer who served as jury foreman, announced the unanimous guilty verdicts in a packed courtroom just after midnight on June 17, 1984. Judge Greg Foote read the verdicts at approximately 1:00 A.M., convicting Diane of first-degree murder, two counts of attempted first-degree murder, and two counts of first-degree assault.
Sentencing and Personality Disorders
Judge Gregory Foote sentenced Diane Downs to a lengthy prison term with a mandatory minimum to ensure she would not be paroled early. Judge Foote imposed consecutive sentences for murder, attempted murder, and assault, resulting in a total sentence of life plus fifty years in prison, with a twenty-five-year mandatory minimum before parole could be considered.
Psychiatric evaluations concluded that Diane Downs suffers from three distinct personality disorders rather than mental illness or insanity. Dr. George Suckow testified that Diane exhibits these conditions, explaining that unlike psychosis or insanity, personality disorders are deeply entrenched in a person's character and cannot be easily cured.
Dr. Suckow presented his psychiatric findings to Judge Foote during the sentencing hearing to support the Dangerous Offender status. The evaluation identified:
- Narcissistic Personality Disorder;
- Histrionic Personality Disorder;
- Antisocial Personality Disorder.
Children Recovery and Escape
Christie and Danny successfully transitioned into loving, stable environments, eventually letting go of their traumatic past. The surviving children were legally separated from Diane and placed in secure homes where they received intensive rehabilitation, eventually thriving in school and activities under the care of the Slavens and the Hugis.
Christie became first chair in her school band playing the French horn and Danny excelled on the trampoline, while both eventually stopped asking about Diane.
Diane Downs successfully executed a carefully planned escape from the Oregon Women's Correctional Center by scaling the perimeter fence during a diversion. On July 11, 1987, Diane climbed the fence at 8:40 A.M., crawled beneath a white Chevy pickup truck in the parking lot, and later hitched a ride with the Hawkins family.
