Authorities say two people have been shot and killed and two others wounded in Mooresville.
Multiple media outlets reported Sunday that the Iredell County Sheriff's Office said it believes the suspect is one of the dead. All four were described as members of the same family.
Officials with the sheriff's office couldn't be reached for additional comment.
Investigators say officers went to the home about 8 a.m. after getting a call from a cell phone. Once inside, officers found the bodies and two with serious gunshot wounds.
The survivors were taken to Carolinas Medical Center in Charlotte.
