YORK COUNTY, S.C. — Channel 9 is learning new details about the murder-suicide that left four people dead, including York County's assistant county manager, Anna Moore.

Authorities confirmed Anna Moore's husband, Randy Moore, fatally shot three people before killing himself at a Rock Hill home Sunday.

A spokesperson for the York County Sheriff's Office told Channel 9 they are working as fast as they can to get more answers for the families of the victims.

Trent Faris told reporters around 5:40 p.m. Sunday police received several 911 calls, including one from a friend who discovered the bodies of Randy Moore, his wife, Anna Moore, her son Jason Lockamy and his girlfriend, Lara Young.

Anna Moore served as the assistant county manager for York County for 10 years

Authorities also said they discovered two bodies outside and two inside of a house on the 900 block of Dunlap Roddey Road.

Neighbors say the couple moved in within the past few weeks.

"Sheriff Bruce Bryant and everyone at the York County Sheriff's Office is saddened about this tragedy. We share the grief with county employees who knew Anna Moore," Faris said.

Channel 9 checked into Randy Moore's background and found a criminal history reaching back to the 1970s showings multiple convictions for DUI and drug offenses. Now that authorities know who pulled the trigger, they're working to determine why the shooter gunned down his family.

Authorities have not released a motive and say they're waiting for all forensic test results before releasing any new information. They expect results in a few weeks.

Channel 9 checked and one of the victims, Randy Moore, had previous DUI and drug related arrests. Lora Young was arrested in 2011 for domestic violence.
