PASSIAC - Four suspects are under arrest after a teenager was shot dead in Passaic Tuesday night.

Police say the victim, Alex Siri, 19, was with friends on Parker Avenue when three cars pulled along side them. They say a gunman got out of one vehicle and began firing. Siri was fatally shot four times.

Investigators believe the accused may have targeted the wrong person. Police are also looking for a man on a bike who apparently thought he was being shot at and returned fire.
