VICTORVILLE — After nearly six years of court proceedings, a jury found a Newberry Springs man guilty of killing his stepfather in 2011, court records show. Jose Luis Fontenot faces life in prison without the possibility of parole when he is sentenced next month.

After deliberating for less than a day, the jury convicted Fontenot of shooting his 71-year-old stepfather in the head during an argument on May 5, 2011. Fontenot believed his stepfather was having sex with his teenage sister.

“On the night of the murder, Fontenot confronted his sister and stepfather about their relationship,” said Deputy District Attorney Shannon Faherty, who prosecuted the case. “Fearing what Fontenot may do, his sister called 911 and stayed on the line with the operator for 24 minutes. At the conclusion of the emotional 911 call, the jury could hear the shot fired that killed Jimmy Handley.”

Authorities responded and found Handley’s body on the porch of his Newberry Springs home. Fontenot had fled, but was arrested the next morning while trying to jump on a train, according to previous reports.

Fontenot, 25, who was also convicted of second-degree murder in September for the slaying of a 46-year-old truck driver in 2009, is scheduled to be sentenced for both murders March 10, court records show.

Fontenot was charged with the slaying of Gregory Boriack, 46, who was found in the parking lot of the Bun Boy restaurant on West Main Street in Barstow with a fatal gunshot wound to his head on Jan. 16, 2009.

Boriack’s murder was a mystery to police and went cold until an inmate who shared a cell with Fontenot came forward with information that linked him to the death, according to previous reports.

Fontenot, while in custody for Handley's murder, confessed to killing a truck driver when he was 17 years old, according to the inmate, who was identified only as "John Doe." According to previous reports, Fontenot and the trucker allegedly got high and watched pornography together in the cab of Boriack's truck.

When the trucker offered Fontenot $40 for sex, Fontenot shot him in the head, the inmate testified. Then Fontenot stood over Boriack as he died, the inmate said, watching the trucker's eyes roll back as he choked on his blood.

A year after his arrest, both of Fontenot’s attorneys stipulated to the court to accept a medical examination report that found him not competent to stand trial after two of three mental fitness reports found him unfit for trial when he was 21 years old. But Barstow Superior Court Judge John Gibson found Fontenot competent to face trial and reinstated his criminal proceedings, according to previous reports.

After deemed fit to face trial, Fontenot, wearing orange neck to toe with handcuffs and a waist-chain, stood up and began walking toward his family and the exit. Fontenot tried to to push past a bailiff, who then took hold of him. The bailiff told Fontenot to stop, but according to previous reports he began kicking and struggling.

Another bailiff threatened Fontenot with a stun gun and told him to calm down. When he didn't, the bailiff shot him in the arm with the stun gun, sounding a loud boom, followed by a family member's scream, according to previous reports.
