Investigation and pre-trial context

Nathan Ybanez’s home life included multiple reports of abuse and attempts to seek help.

In late 1997, Nathan told friends his dad was beating him. Parents of a schoolmate alerted police that they believed he was being abused. Nathan also called the Douglas County Sheriff’s Office after wandering the streets for two days and requested social services be contacted for relocation. An officer wrote that Nathan was unable to live at home and would not explain why he had run away. The deputy returned Nathan to his mother, and the Sheriff’s Office refused to discuss whether child welfare workers were called.

Eight months later, Nathan killed Julie Ybanez in Highlands Ranch with a fireplace tool.

At least two runaways were documented in Douglas County Sheriff’s Office records. Nathan was returned after one midnight dash to the Bakers’ house, where he arrived crying. Nathan described a raging father who had shaken him awake, trashed his room, thrown him against a wall, and choked him while his mother stood by.

His parents placed him in a mental hospital, Centennial Peaks in Louisville. His psychologist, Dr. Rich ard Spiegle, later addressed hospital records reporting a “choking” incident.

Relatives said Julie was obsessed with tracking Nathan’s movements. Julie told Pat Jensen, Erik’s mom, that she feared Roger would hurt Nathan.

The Bakers and Jensens discussed concerns and took them to Douglas County Social Services offices, filling out a report and telling a caseworker authorities should investigate Nathan’s home life. Curt Jensen said they never heard from an investigator.

Arrest and discovery at the scene

At about 4 a.m. on June 6, 1998, a Douglas County deputy steered his patrol car into Daniels Park in Highlands Ranch and saw a blue Lexus with its headlights on. The trunk lid was open and Nathan stood next to a sleeping bag. Inside the sleeping bag was Nathan’s dead mother. Nathan had planned to bury her in the park.

Nathan’s parents had told him earlier that morning that they had decided to send him away because they would not tolerate his running away and drug use.

A police officer on patrol spotted Nathan in a public park standing over his mother’s body the next morning after the killing.

Trial

Charges and posture of the case

Nathan Ybanez was charged as an adult with first-degree murder. The Douglas County district attorney bypassed the juvenile justice system by filing first-degree murder charges in adult criminal court.

The defense insisted that, although Nathan played a part, he was not guilty of first-degree murder like Erik Jensen. The defense argued Jensen was the real instigator and Nathan was a follower. The defense also sought to reduce the conviction to a lesser charge.

Defence representation and trial conduct

Craig Truman was Nathan Ybanez’s trial lawyer. The trial lasted less than three days and was televised on Court TV. Truman called no witnesses on Nathan’s behalf. In the closing arguments, Truman asked jurors to hand Nathan a second-degree murder conviction instead of first-degree, and the jury returned a first-degree murder guilty verdict.

A conflict was described in trial proceedings. The tension between father and son became publicly evident by an audio tape played during a motion to throw out Nathan’s confession, in which Roger is heard cursing him angrily before storming out of the room.

Terrence Johnson later said Nathan “basically” walked into trial with “absolutely no chance of winning” because of ineffective assistance and conflict issues. The account included that the father was allowed to guide the defense process.

Evidence and testimony mentioned

The prosecution argued Nathan acted with deliberation, using fireplace tongs to beat and strangle his mother during a struggle. Prosecutors said Nathan and Erik phoned for help cleaning up after the murder.

Brett Baker testified on premeditation and post-crime involvement. Baker testified that Nathan remarked beforehand that he was going to kill his mother, which the prosecution used to support premeditation. Baker also testified that Jensen described after the murder how he had helped Nathan kill Julie.

Prosecutors put Roger Ybanez on the stand. During trial testimony, Roger briefly admitted to a fight he provoked with his son, including grabbing Nathan and throwing him up against the wall and telling him he needed to pay attention.

Truman mocked the notion of abuse briefly during defense argument, quoting friends as saying Roger “can’t discipline you,” and Nathan “can” have rights and that “you’re being abused, and we’re going to help you,” which was described as influencing Nathan’s belief.

Verdict

A jury convicted Nathan Ybanez of first-degree murder. The verdict triggered mandatory life without parole.

Sentencing

Nathan Ybanez was sentenced to life in prison without parole. The sentencing outcome is stated as occurring on January 27, 2000.

Appeals and post-trial developments

Nathan Ybanez planned to appeal his conviction based on ineffective assistance of counsel. His new lawyers and family members stated that he had been “steamrolled” by the legal system and that his father, the alleged abuser, was allowed to guide the defense process.

In prison interviews and investigations:

  • Jeff Pagliuca, Erik Jensen’s new lawyer, interviewed Nathan in prison and quizzed him about his background in search of indications of abuse.
  • Nathan skirted questions about his background; Pagliuca later concluded that Nathan fit a profile of a sexual-abuse victim and shared those findings with the Jensens.
  • Terrence Johnson agreed to begin investigating the conviction and family history and enlisted Dr. Rich ard Spiegle, a forensic psychologist and former child therapist.

Dr. Rich ard Spiegle described an investigative approach that included initially assuming many kids were lying and trying to get out of trouble. He said Nathan seemed credible, noting that sexual-abuse victims may not trust people, may be slow to reveal secrets, and may have difficulty remembering due to physical and sexual trauma.

Spiegle identified scars on Nathan’s back after Nathan lifted his shirt with hesitation. Spiegle said the scars likely were lashings and sought expert examination at the Kempe Children’s Center in Denver, and the expert ruled the marks were likely caused by lashings.

In later therapy sessions and correspondence, Nathan described accounts of abuse, including claims of sexual assaults. Dr. Rich ard Spiegle later said Nathan testified in a court hearing that his mother forced him to have sex with her in a Disneyland hotel and that his father forced him to have oral sex with him during showers.

Roger Ybanez denied sexually abusing Nathan and denied sexually or physically abusing him, while acknowledging instances where witnesses described him acting violently and demeaningly toward Nathan, including shoving, grabbing, throwing, and striking with objects at a young age.

Imprisonment and other records

Nathan Ybanez was described as having earned his GED and practicing meditation in prison. He told FRONTLINE he was “better in prison” than when he was free. He and Erik Jensen developed writing and visual art talents while serving time.

Nathan wrote prison journal excerpts that discussed daily life, including canteen day, shake-downs, lockdowns, sleep and fatigue, prison conditions, and education access.

In journal excerpts:

  • He wrote about prison life and canteen day routines, including “shake-down” descriptions where guards tore everything in his cell up looking for stuff they could take.
  • He wrote that he had never been forced to stab anyone and “haven’t been raped” (stated in the prison journal excerpt).
  • He described prison work, education programs, and college class access rules including age and parole eligibility criteria.
  • He described prison facilities and living arrangements, including cell dimensions and lack of space, and described rules about water and washing clothes.
  • He described being in ad seg (solitary) and described placement of metal plates on windows in ad seg.
  • He wrote about isolation and concerns about people being moved.
  • He described fear and frustration triggers and his views on prison violence and suicide attempts observed by him.

A journal excerpt dated 4/14/05 included the line “This was a good person with a good mind who was destroyed as a child,” attributed to Dr. Rich ard Spiegle in the broader narrative about scars and psychological impact. Another journal excerpt included a line attributed to Nathan about prison life being “like Chinese water torture” and about studying law for a chance to get out.

Nathan described being 24 at the time the journal excerpts were discussed, and that he entered prison at 16.

    • Paul Mones was quoted: “For many years nobody could understand why a kid could kill a parent,” and “Now we know that in most cases it's inextricably related to their treatment by parents.”
