Lawrence Nathaniel Jones, an employee of a poultry processing plant, opened fire at his place of employment on November 6, 2012. Jones killed two workers and wounded two others during the shooting. He also killed himself after taking out his targets.
Though his motivations at the time were unclear, a 2004 Fresno County mental health evaluation diagnosed Jones with intermittent explosive disorder, drug-induced psychotic disorder and dependence on multiple substances including amphetamine, marijuana and alcohol, according to The San Diego Union-Tribune.
"He had opportunity to shoot other co-workers that were in the business at this time, but he chose not to," Fresno Police Chief Jerry Dyer said at the time. "He walked around them in order to get very close to the intended targets, place the gun very close and fire a round."
Jones had an extensive criminal background, which included robbery, vehicle theft and a handful of other convictions. Police later found several firearms in Jones’ apartment, one of which was a particularly rare style of gun, leading them to believe the weapon may have been stolen.
"We are still trying to follow up on some rumors regarding a dispute between Jones and one of the other co-workers, but we have not been able to verify it at this point," Dyer said in the days following the incident.
