Halifax police have charged a fourth person in a May murder on Clifton Street.
Jason Matthew Halsley, 27, was arrested without incident in Clayton Park.
Two men broke into an apartment at 2711 Clifton St. on May 25 at about 8:40 p.m. One of them was armed with a handgun.
Two people in the apartment were shot: Corey Dwayne Lucas died at the scene, and William Hawes-Boliver was shot in the leg.
In the days after the fatal shooting, Hawes-Boliver told CBC News the ordeal began when two men stormed into his home. He said one of the intruders shot him in the leg with a silver .25-calibre automatic handgun before turning the weapon on Lucas.
Halifax Regional Police have said the shooting was related to drugs and was not random.
Last month Dylan Peter Roach, 20, was charged with first-degree murder and attempted murder, and Jenna Karlene Piercy, 27, was charged with accessory after the fact.
Simon Peter Dugas, 27, was charged Tuesday with first-degree murder and attempted murder.
On Wednesday — less than 24 hours after he was arraigned — Halifax Regional Police announced the original charges against Dugas were withdrawn and replaced with a new allegation of being an accessory to murder after the fact.
