KEYPORT — A manhunt unfolded Tuesday after a reported stabbing by the Stop and Shop in Keyport, police said. As of 4:45 p.m., multiple K-9 units and a State Police helicopter were involved in the search for a person of interest, as seen in photos shared by police in both Keyport and Hazlet. The man was described by police as a white male with grey hair, wearing either a blue or red hat and blue or red shirt, according to Keyport police.
