26-year-old Tyler Brehm of Carlisle, Pennsylvania had been in Los Angles, California about a month when he went on a shooting rampage. Brehm was walking in Hollywood when he began firing a .40 caliber Smith & Wesson handgun into the air. He threatened motorists in a McDonald's parking lot and then walked to the intersection of Sunset Boulevard and Vine Street. He fired several shots at a silver Mercedes-Benz, striking music executive John Atterberry in the neck and face. Atterberry died of his injuries a few days later.
Brehm stood in the middle of the intersection, firing at cars. Several drivers had their car windows shot out. The shooting ended when LAPD confronted Brehm and ordered him to drop his gun. When he pointed his weapon at an officer police fired. Brehm was pronounced dead at the scene.
Brehm was unemployed. Police said that he had no criminal record. Some speculate that a recent breakup with his girlfriend led to the shooting.
