NORWALK - Norwalk police held a press conference today about the fatal shooting of a 19-year-old man last Friday, which marked the fifth murder in the city so far this year.

Norwalk Police Chief Harry Rilling says investigators are doing everything they can to find the person who gunned down Amos Brown Jr.

Police say Brown was found shot in the head on Lexington Avenue more than a year after he was acquitted of a Bridgeport teen's murder. Brown's family believes he was killed in retaliation.

A rental car was found yesterday in Bridgeport, which police say could be connected to Brown's murder.

Police say they've increased patrols and surveillance in Norwalk's violence-prone areas.
