Last week’s fatal shooting in Berkeley began as a road rage incident on University Avenue, according to court papers released Friday shortly after charges were filed in the case in Alameda County Superior Court.

Authorities have arrested the man they believe fatally shot a stranger on Chestnut Street in Berkeley on Friday afternoon.

The man who was killed while driving in Berkeley on Friday had his younger sister in the car when he was attacked, according to community reports. There was no indication Saturday that the assailant knew the victim.
