Hemet man accused of murdering cellmate ordered to stand trial
INDIO, Calif. — A felon in custody on a fugitive from justice warrant who stands accused in the bludgeoning death of his cellmate while being housed at the John Benoit Detention Center in Indio last July was ordered yesterday to stand trial for the man’s brutal murder.
The murdered inmate, John Hemmer, 48, of South Dakota, was awaiting trial after being arrested on attempted murder, kidnapping, torture, false imprisonment, and other charges following a domestic violence-related attack at a Desert Hot Springs KOA campground in 2019.
His cellmate, Luke Hanchette, 42, of Hemet, was the only other person in the two-man cell and was soon charged with Hemmer’s murder.
LEADING THE RCNS HEADLINES:
Hanchette appeared at the Indio Larson Justice Center on Wednesday for the second half of a preliminary hearing that began earlier this month.
During the proceedings, Riverside County Superior Court Judge Anthony Villalobos found there was sufficient evidence for him to stand trial on the murder charge, as well as a sentence-enhancing allegation of using a deadly weapon – described in court as a metal crutch, during the commission of a felony.
He was ordered to return to court for a post-preliminary hearing arraignment next month, on April 6.

At the time of the murder, Hanchette had been in custody following his July 2019 arrest based on a fugitive from justice warrant that alleged an assault resulting in great bodily injury and a prior felony conviction enhancement. No details regarding the incident that led to that arrest by City of Hemet police officers were immediately available.
As reported by RCNS at the time, on July 21, 2021, deputies were conducting a routine security and safety check of the inmates at the Indio jail facility shortly before 8 a.m. when they discovered an unresponsive inmate with “significant injuries” inside a two-man housing unit. A bloody and damaged metal crutch was also found within the cell.
Although deputies and other jail staff members immediately began life-saving measures, which were later continued by paramedics, Hemmer succumbed to his injuries and passed away inside the housing unit.
Officials have not said what may have led to the deadly attack.
