Four people are dead in what investigators believe was a triple murder-suicide Tuesday night in a DeKalb County neighborhood.

Three of the victims, two women and a man, were found in the driveway of a home on Isle Royal Court in unincorporated Stone Mountain when officers arrived at 9:10 p.m., according to DeKalb police.

They were identified by police on Wednesday as Whitney Nolbert, 33, Lanisha Mitchell, 28, and Daniel Price, 40.

The fourth was found dead at a residence about a mile away, officers at the scene told Channel 2 Action News. Investigators believe that man, identified as 62-year-old Howard Jackson, shot and killed the other three before driving to his own home and turning the gun on himself.

All the parties involved knew each other, police spokesman Sgt. J.D. Spencer told AJC.com. Officers told Channel 2 that Jackson may have been in a relationship with either Nolbert or Mitchell.

“Investigators have determined that there was an argument and the suspect shot all three victims,” he said.

Anita Price, the mother of Daniel Price, told the news station that her son left to walk next door to talk to a woman, and he never came back.

“My baby got caught in the crossfire or whatever was going on,” she said.

The shooting happened in Stone Mountain and may people witnessed the violence.

A neighbor told Channel 2 she heard a series of quick shots before she looked over her fence to see three bodies.

“Maybe 15 shots, and then it would pause, and then it started back,” Phlendetha Grier said.

GoFundMe pages were created to help Price's family and Mitchell's family with funeral expenses.
