Story highlights Suspect is dead and was heavily armed, police say

Family told police he had been "bingeing on cocaine"

Azusa, California (CNN) The man suspected of fatally shooting one man and wounding two women Tuesday near a Southern California polling station had been "bingeing on cocaine," police said.

The 45-year-old suspect lived in Azusa, a suburb of Los Angeles, where the shooting happened. His family told police that he had been heavily using cocaine and that they left to get away from him on Monday night.

On Tuesday afternoon, the man opened fire in his neighborhood and began shooting at random cars and passersby, killing his 77-year-old neighbor and wounding a woman, police said.

He later ambushed police when they arrived on scene, said Lt. John Corina of the Los Angeles County Sheriff's Department.

The third victim may have been hit during the ensuing gunfire -- leaving two women, ages 65 and 59, in critical condition. One of the women was shot in the face, and the other in the torso. Police said they had no identities for the three victims.
