NORWALK - Police say witnesses are coming forward in the death of a teenager last week.

AJ Brown died after he was shot in the back of the head Friday.

His family believes it was retaliation for a 2008 death. In that case, a jury found Brown acted in self defense when he stabbed Tykwon Hunt, 17, at a party.

Police say they are following up on the leads generated by the witnesses.
