Genesis HealthCare
A mother and her son were killed in a murder-suicide inside a New Jersey assisted living facility Sunday, according to officials.

The shooting occurred around 5:45 p.m. inside the Genesis HealthCare facility on the 3000 block of East Evesham Road in Voorhees, New Jersey. Police say George Buller III, 62, of Lumberton, shot his mother, 85-year-old Andree Buller, inside her room. He then turned the gun on himself just as a nurse's aide walked in, investigators said.

The man and his mother were both pronounced dead at 6:08 p.m. Police say Buller had visited his mother at the facility in the past.

No one else was hurt during the incident. Staff members cleared the wing and moved the residents to a safe place as police investigated.

Voorhees Township Police Deputy Chief Bill Donnelly told NBC10 no one heard any yelling or argument moments before the shooting. Police are trying to determine how and why a gun was brought inside the facility.

"It's unknown exactly where the gun was or if he did go out to retrieve the gun," Chief Donnelly said. "At this point that's what we're speculating because he did leave the facility and come back inside."

The facility is home to patients receiving short- and long-term care as well as those receiving cardiac management, dementia and Alzheimer's care. Genesis is based in Kennett Square, Pennsylvania. It operates more than 500 centers in the country.
