The family of Natasha Warren held a tearful press conference Tuesday to beg for witnesses to come forward in the August 2008 death of the 23-year-old woman.
Warren was last seen alive around 11:30 p.m. on August 22, 2008, at a Sunoco convenience store on Bush River Road. She had been on her way to work the nightshift at the downtown post office when her car blew a tire on I-26. She went inside the convenience store four times during a 45-minute period.
After two years of chasing leads, Richland County Sheriff's investigators said they are running short on clues.
They released a photo Tuesday of a man who stopped in the convenience store the night Warren was killed. The man, who is wearing wide-striped shirt in the video, told clerks he was a bounty hunter, said Capt. Stan Smith, an investigator. He offered people in the store money for their assistance in helping him track down a couple that was wanted, Smith said.
Investigators have weeded out other potential suspects. They believe Warren's killing was a random act, Smith said.
"She was in the wrong place at the wrong time," he said.
Warren made her last trip inside the convenience store to ask for more change for the phone around 11:30 p.m.
An S.C. Highway Patrol trooper the next day discovered her body with a gunshot wound. Some of her personal belongings were missing.
Warren's family hoped their pleas for a break in the case would touch somebody who had information or saw Warren that night.
"It's time for this case to come to an end," said Delois Warren, the mother. "Somebody knows something. Please say something. I don't know how much more I can take."
Delois Warren broke down into sobs and other family members stepped up to finish her request for help.
"This situation could happen to any one of us," said Deirdre Mitchell, a cousin.
