David Brown Jr., who killed a police officer and another man on Father’s Day in Lancaster, had traces of marijuana, alcohol and PCP in his system, according to a toxicology report released Wednesday.

Brown Jr. is the son of Dallas Police Chief David Brown and died in the Father’s Day shootout after he killed Lancaster police officer Craig Shaw, 37, and unarmed father Jeremy McMillian, 23.

The Dallas County Medical Examiner’s autopsy report outlines levels of marijuana and phencyclidine in Brown Jr.’s system, after blood tests and drug screens were administered.

Phencyclidine is a dissociative drug often called PCP or angel dust that causes intense hallucinations and erratic behavior. When Brown Jr. opened fire, he was wearing only sunglasses and boxer shorts. Witnesses reported Brown Jr. acting strangely before the shooting.

His alcohol level was revealed to be .01 and was shot nine times in the neck, head and torso, the autopsy revealed.
