Peel police have issued a first-degree murder warrant in the fatal shooting of a 23-year-old Mississauga man at a house party over the weekend.

Police are looking for 19-year-old Jason Hay, of no fixed address, in connection with the slaying. Investigators are urging Hay to contact a lawyer and surrender.

David Latchana died after being shot in the head at about 3:45 a.m. at a home in Malton region on Saturday. Police believe the attack followed a shouting match.

Hay is believed to have fled the scene in a dark-coloured vehicle, possibly occupied by two to three other males. The suspect should not be approached as he is considered armed and extremely dangerous.

Anyone with information is asked to contact police at 905-453-2121 ext. 3205, or Crime Stoppers at 1-800-222-TIPS (8477).
