The Los Angeles County Coroner's Office identified the shooter as Tyler Brehm, 26, of Hollywood.
HOLLYWOOD, Calif. (KTLA) -- The ex-girlfriend of the man police killed Friday after he shot at motorists and pedestrians told KTLA 5 that a recent break-up may have triggered the man's rampage.
Brehm and Alligood went to school together in Pennsylvania, beginning in junior high, continuing in high school. They began "hanging out" during their college years, she said.
Alligood described Brehm as a "humanitarian," and someone who was "extremely motivated to change the world for the better." He even managed a non-profit organization for a friend, she said, but would not name the organization.
She said Brehm was "really stressed out lately." He met a woman he thought was a pharmaceutical saleswoman, who had given him some kind of pills, Alligood said. He began taking the pills, which was alarming because he never took "hard" drugs before.
"He was very anti-pharmaceutical," Alligood said.
After Brehm met the woman -- who Alligood would not name -- he was never the same.
Los Angeles Police Department officials say the motive to Brehm's shooting rampage is still unknown.
