On Friday night, a man in a mask robbed the Marquee Cinema at Wakefield Commons at gunpoint.
The man shot and killed the theater manager, 48-year-old Mark Buhaug.
Police say they're looking for 40-year-old Anthony Bimbo. They believe Bimbo is also responsible for a robbery in Wake Forest on Saturday morning.
Police already arrested 18-year-old Jason Zilinski and 19-year-old Ryan Becker in connection with the shooting.
