Brandi Nicole Jordan, 23, of Gaston, was shot in the chest by her live-in boyfriend, Travis Blease Miller, 36, before he shot himself in the head, according to Aiken County Sheriff's Office.
Miller's mother, Stella, told officers the couple had no electricity or air conditioning at their mobile home at 270 Blue Poppy Road in Batesburg, and that had led to previous arguments. The couple, who had lived together for about six months, had stretched an extension cord from Miller's mother's home at 278 Blue Poppy Road.
Miller and his mother were arguing at her home when she told her son to leave, just before 11 a.m. After he headed back to his trailer, Stella Miller heard a loud bang, said Aiken County Coroner Tim Carlton.
She told police she ran to the trailer, where she found her son disoriented and trying to perform CPR on Jordan, who was on the floor of the bedroom, Carlton said.
She walked outside and called 911, but didn't give officers information about who was shot or the circumstances of the shooting. Then she lost her cell phone signal.
Stella Miller told authorities she heard a second shot a few minutes later. She called 911 again, but didn't return to the trailer. Officers later found Travis Miller on the bed.
No additional information on their deaths was gathered from the autopsy on Thursday, Carlton said.
Although Travis Miller had a history of drinking and pleaded guilty to a felony DUI in 1997, Carlton said nothing in the house made him think Miller was drinking before the shootings.
"It's just one of those cases where we won't know what transpired in the minutes leading up to the argument," Carlton said.
"Unfortunately no one can tell us what happened," said Sheriff's Capt. Troy Elwell.
