Los Angeles (CNN) -- Authorities on Saturday identified a gunman killed by police after he opened fire at passing vehicles along a downtown street in Hollywood.

But they said they don't know why Tyler Brehm, 26, went on a surreal shooting rampage captured on amateur video Friday.

The video shows Brehm walking down Sunset Boulevard, wielding a handgun and firing at vehicles, seemingly at random. Brehm fired a "significant number" of rounds, wounding three, police said.
He then returned to an intersection, where he was confronted by a plainclothes police detective and an off-duty police officer working on a nearby movie set, officials said.

"At that point the police ordered him to drop his weapon and he pointed his gun at the police and an officer-involved shooting occurred," police spokeswoman Sgt. Mitzi Fierro said on CNN.
Brehm died at a nearby hospital, a police statement said.
