RENO, Nev. (AP) — A 22-year-old carjacker who stole a Nevada state trooper's cruiser then fatally shot himself in the chest with the patrolman's shotgun was on probation in Florida for carrying a concealed weapon.

Investigators confirmed Wednesday that Devin Peterson of Jacksonville, Fla., appears to have died from a single, self-inflicted gunshot wound after carjacking a second vehicle and leading police on a chase Monday on Interstate 80 east of Reno.

Florida Department of Corrections records show he was convicted of the felony gun charge in April 2011 and was sentenced to three years' probation.

Peterson fled after he and three other Jacksonville residents were pulled over and state troopers searched their SUV for marijuana. Their bail at the Washoe County Jail is set at $150,000 each on drug and conspiracy charges.

The man who hijacked a Nevada state trooper's cruiser and used the patrolman's shotgun to carjack another car before allegedly committing suicide appears to have died from a single, self-inflicted gunshot wound to the chest, investigators said Wednesday.

Initial reports from the Nevada Highway Patrol that indicated the victim shot himself multiple times were incorrect, Lyon County Sheriff's Lt. J.L. Pattison said. He said the coroner's report is not official yet, but it's clear there was only one gunshot wound.

"Unofficially, it is self-inflicted," Pattison told The Associated Press. "There is only one shot. A shotgun is pretty effective."

State troopers fired shots at the suspect as he fled in the stolen patrol car Monday afternoon near the Mustang exit on Interstate 80, about 5 miles east of Reno. But Pattison said no law officers fired their weapons at the scene where the victim shot himself near Fernley, in Lyon County, about 15 miles farther east.

"The only shooting that took place in Lyon County was the suspect that shot himself in the chest. There was no law enforcement shooting at that scene," he said.

The Lyon County sheriff's office is acting as the coroner conducting an independent investigation into the death of the victim, who was a passenger with three other people in a 2013 Ford Explorer with Florida plates that was pulled over by two troopers just before 4 p.m. Monday. The small, rural county does not have a coroner's office. Continued...
