DALLAS — An autopsy report shows that David Brown Jr., the son of the Dallas police chief, was high on drugs when bullets started flying at a Lancaster apartment complex on Father's Day.

Brown, 27, is blamed for the shooting deaths of Lancaster police Officer Craig Shaw and another man before Brown was killed by police.

The autopsy report was finished rather quickly. Normally these types of reports take months, but the Dallas County Medical Examiner's office released it on Wednesday, 11 days after the crime.

The report says David Brown Jr. had marijuana and PCP in his system when he died.

The autopsy found Brown had 0.12 milligrams of PCP in his system and also a small amount of marijuana. Experts tell News 8 that even a slight amount of PCP can have psychotic effects.

Parkland Memorial Hospital toxicologists told News 8 the levels in Brown's system were high, and are consistent with other cases they have seen where people have gone crazy and done violent things.

They said PCP can cause bizarre behavior and intense hallucinations.

On June 20, the day Brown gunned down an officer and an innocent man, witnesses said he had been acting erratically. He got into a fight with his girlfriend, Misti Conaway, and had been shouting and yelling at people at his apartment complex before he began shooting.

The autopsy results also show Brown was shot nine times by Lancaster police, who opened fire on him after he shot and killed Officer Shaw.

News 8 has also learned that back in 2004, Rowlett police arrested Brown. He was booked as a mental health patient and was ordered into a psychological assessment program.

It is not clear whether Brown completed that program, or why police and health care workers felt he suffered from mental health problems.
