Shooter in Fresno plant murders was diagnosed with “intermittent explosive disorder”
The ex-convict who killed two co-workers and wounded two others at a Fresno, Calif., processing plant this week had been diagnosed with “intermittent Explosive Disorder,” police say. They added he also had dependences on multiple substances including amphetamine, marijuana and alcohol, reports ABC News.
Intermittent explosive disorder is a condition marked by sudden aggression that appears out of proportion to any external stress, according to the National Institute of Mental Health. To be diagnosed with it, a person must have had three such aggressive episodes. Lawrence Jones, who was employed by Valley Protein, was diagnosed with the condition during a mental health evaluation in 2004.
