Boise man accused of stabbing stranger was released from prison 4 months ago

BOISE (Idaho Statesman) — The man accused of stabbing a stranger in the face, hands and neck multiple times on Wednesday was released from prison only four months ago. Ruben Diaz still had 19 years to go before he would have finished serving his parole for previous violence.

Diaz, 36, remains in the Ada County jail on suspicion of stabbing a 74-year-old man in Southeast Boise, according to Boise Police. He has been charged with attempted murder, and his bond has been set at $1 million.

The victim was still hospitalized on Friday. His family set up a GoFundMe page to request help with his medical bills.

“Major tendon and nerve damage to (the victim’s) hands and fingers took place while frantically trying to shield the knife attacks from his face and neck,” the GoFundMe states. “He was unable to block all of the strikes to his face, the worst being a blow to his right cheek that severed the facial nerve to his mouth, limiting his facial movements on that side.”

Diaz was arraigned Friday and has been appointed a public defender. Magistrate Judge Karen Vehlow ordered a psychological examination to determine his fitness for trial during the court appearance.

Vehlow also granted a no-contact order stipulating Diaz must stay 500 feet away from the victim and the victim’s address.

What happened?

The alleged assault occurred just before 11 a.m. in the 3900 block of Preamble Place.

Deputy Prosecutor Tamera Kelly on Friday said the victim was outside his home raking leaves. Diaz asked the victim for directions, she said, and “right after that started stabbing and slashing the victim’s head and face multiple times.”

Diaz later admitted to law enforcement that he had bought the knife that morning “for the sole purpose of trying to kill someone,” Kelly said.

When police arrived, they said Diaz was still assaulting the man. Two officers struck him with stun guns after he defied orders to drop the knife.

This isn’t the first violent crime Diaz has been accused of. In 2008, he was sentenced on two counts of aggravated battery in Bonneville County. He was ordered to serve up to 30 years in prison for one count that had a weapon enhancement, and up to 15 years in prison for the other count.

The judge in the Bonneville County cases, 7th District Judge Jon Shindurling, ordered Diaz to serve two years and six months for each charge before he was eligible for parole, according to Bonneville County records. Ultimately, he was in prison 10 years before he was released.

A history of problems

The Idaho Statesman reviewed Diaz’s prior cases on Friday and found that Diaz has a court-ordered conservator because of developmental delays and mental illness. He has been diagnosed with autism and schizophrenia.

In 2008, Diaz’s mother, Sandra Kaiser, was appointed his legal guardian.

On Jan. 24, 2017, the state parole commission granted Diaz his release. He was still imprisoned as of September 2017, when Kaiser petitioned a judge to review her son’s detention — noting the commission’s decision.

Her petition files included a copy of the parole decision. It said Diaz would be released upon completion of programming, but only to an assisted living facility. Special conditions of his release included that he take medication, according to the document.

Kaiser’s request for a writ of habeas corpus was ultimately dismissed — such a petition can only be filed by the inmate himself or by an attorney, not by a legal guardian, the judge on the case ruled.

Sandy Jones, executive director of the parole commission, told the Statesman in an email Friday that the reason it took so long to release Diaz was because “it took that long to find him a suitable residence and arrange for his disability benefits.” She said those requirements are common if an offender has clear disabilities and no reasonable family support.

Diaz since July has lived at the Hancock House, a small, eight-bed assisted living facility at 1322 Hancock Drive in Boise, a state correctional spokesman confirmed. The facility is only a few blocks away from where the stabbing incident occurred at the victim’s home.

The Statesman on Friday requested copies of documents connected to the Bonneville County assaults, but did not receive an immediate response.

The victim’s family declined to be interviewed on Friday, saying they were awaiting further police investigation.

“My father is a model citizen, diligent American, Vietnam Vet and most importantly has the characteristics of a good man,” the GoFundMe states.

Diaz’s next scheduled court appearance is a preliminary hearing at 8:30 a.m. Nov. 15. During such a hearing, a magistrate judge decides whether there is enough evidence to send a case to district court and a full trial.
