The trial of Chicago police officer Jason Van Dyke for the murder of Laquan McDonald will continue into next week.
Thursday his defense called an expert in pharmacology as one of their witnesses, along with a neighbor of McDonald's relatives and a former police academy firearms trainer.
Court recessed shortly before 1 p.m. Thursday. There will be no court on Friday. Testimony will resume Monday, Oct. 1.
Dr. James O'Donnell testified about PCP and its effects, and how it can cause rage, aggression and delusions. An autopsy later found McDonald had PCP in his system.
The firearms trainer testified that officers are taught to eliminate the threat and reload automatically.
The defense tried to trace McDonald's steps on the last day of his life and how he was behaving. They called Yvette Patterson, who lives on the West Side near McDonald's relatives, to the stand.
Patterson testified McDonald asked to see and use her car as she pulled up to her home at about 2 a.m. that morning. She told him she didn't know who he was and then called 911 after a polite exchange with the teen.
