The gunman suspected of slaying eight people at a North Carolina nursing home was stopped by a single shot to the chest fired by a decorated police officer responding to a 911 call.

Carthage Police Chief Chris McKenzie said Monday that police are still working to uncover the motives of 45-year-old Robert Stewart for a rampage in the Pinelake Health and Rehab center on Sunday that claimed the lives of seven residents and a nurse.

It ended when 25-year-old Officer Justin Garner wounded Stewart in a hallway. Garner was wounded in the leg and Is expected to return to the force after he recovers.

Court records said Stewart is not scheduled to appear in court until next week on eight counts of first-degree murder and a charge of felony assault of a law enforcement officer.
