"There's a man who just shot a guy inside Target," says the first caller - not realizing the victim was a woman.
"I heard several shots," said another caller.
Detectives say 67-year-old Mervin Carroll Mims walked into the Super Target store in the Beaver Creek Commons shopping center off Highway 55 around 11:30 a.m. Sunday and shot 58-year-old employee Guadalupe Rosas of Apex.
Rosas had just opened a new cash register when the attack happened. Witnesses said Mims didn't say anything - just shot Rosas multiple times. Mims was still in the store when police arrived. An Apex police spokesperson said officers challenged him and told him to put down his pistol. Instead, he pointed the gun at his head and took his own life.
Mims' daughter - Angela Daugherty of Alachua, FL - says her father had prostate cancer that had metastasized and was terminal.
Daugherty said news of the shooting has been devastating.
“He has grandchildren that do not know he is a murderer. We are all hurt by this,” she said.
While police said Mims and Rosas had been in a relationship that ended in 2005, Daugherty said her father had seen her occasionally since coming to North Carolina.
Mims was apparently homeless and had been living in his pickup truck. Records show he'd bounced around through several states over the past few years. His truck had California tags.
