Officials are releasing little information about the shooting deaths of four people at a South Carolina home, stopping short of calling the incident a murder-suicide even though authorities have said they weren't seeking a suspect after discovering the bodies.

The York County coroner's office told local media late Monday that autopsies are not yet complete. A sheriff's spokesman said no details would be released until the autopsies are done.

The victims in the Sunday night incident were 50-year-old Assistant York County Manager Anna Hubbard Moore; her husband, 55-year-old Randy Eugene Moore; her son, 31-year-old Jason Lockamy of Hamlet, North Carolina; and his girlfriend, 31-year-old Lora Kathryn Young of Fairmont, North Carolina.

Neighbors said the Moores had just moved to the home.

Who fired the shots or any potential motive are still unknown.
