BARSTOW A Newberry Springs man already in custody for the murder of his stepfather in May was arrested Thursday afternoon on suspicion of fatally shooting a San Diego truck driver in 2009.

Gregory Boriack, 46, was found on Jan. 16, 2009 in the parking lot of the Bun Boy restaurant on West Main Street with a fatal gunshot wound to his head. Restaurant patrons called police at 10 a.m. that morning after seeing broken glass and blood in the truck.

According to Barstow Police Sgt. Andy Espinoza Sr., there had been property missing from the cab of Boriack's truck. Police had gotten some leads in the case but were unable to find a suspect.

On Oct. 10, 2011, police received information from a witness in Boriack's death, said Espinoza. After speaking to other witnesses in the case, police were able to identify Jose Fontenot, 20, as the suspect in the Boriack case.

Fontenot would have been 17-years-old at the time of Boriack's death.

Fontenot is already in custody and has been charged with murder in another fatal shooting.

Fontenot was charged in May for the murder of his stepfather, 71-year-old Jimmy Handley in Newberry Springs. Deputies had responded to a 911 call the evening of May 5 from someone reporting that Fontenot had a gun and was arguing with his stepfather.

When deputies arrived, they found Handley dead on the porch of his home. Fontenot had allegedly fled the scene, but was arrested the next morning while trying to jump on a train.

Espinoza said there are some obvious similarities between the two victims, although he did not elaborate on what those were.

Fontenot was interviewed by detectives and arrested for Boriack's death around 4:30 p.m. Thursday, said Espinoza. He is expected to be arraigned Monday or Tuesday.

In the case of Handley's death, Fontenot is being examined by medical doctors and the criminal case against him is awaiting the results of a third doctor's examination. Fontenot's next scheduled date in court in the Handley case was set for Nov. 9.
