Matthew Calton, 53, had been at WakeMed since Nov. 23. That's when police say he was hurt in a shootout with officers trying to take him into custody.
Calton is accused of killing Jay "Jody" Simmons outside Carquest on East Millbrook Road.
About six hours later, Calton was involved in the shootout at the Creedmoor Crossing Shopping Center, on West Millbrook Road.
An officer was also hurt in the scuffle.
Simmons was Calton's landlord. Police said it is still unclear what caused Calton to shoot Simmons.
Calton is expected in court Tuesday.
