A gunman who fired at cars and shouted "kill me" and "I'm gonna die!" was shot to death Friday by police after wounding a driver in the heart of Hollywood, authorities and a witness reported.

The unidentified man was pronounced dead at the scene. No officers were hurt, Los Angeles police Officer Cleon Joseph said.

Police had few details. However, witness Oscar Herrera told KABC-TV that he saw the gunman walking down the middle of Vine Street near Sunset Boulevard, firing at least nine shots into the air and at passing cars while shouting "Kill me!" and "I'm gonna die!"

"People were running all over," Herrera said. "People was ducking."

The driver of a Mercedes-Benz was wounded and taken to a hospital in unknown condition. A truck and another car were stuck with bullets.

The gunman eventually ran out of bullets and pulled a knife before a policeman shot four or five times at the attacker, Herrera said.

Dave Pepper told KCAL-TV that he was in his car when the gunman attacked him.

"This guy came running across the street and he put the gun right up to this window," Pepper said as he sat in the car. "Why he didn't pull the trigger I don't know ... I thought maybe he was out of bullets."

Investigators were trying to determine a motive for the attack. The area was cordoned off and the gunman's body remained in the street under a white sheet more than an hour after the attack.
