WINSTON-SALEM, N.C. (WGHP)— Police say an ex-gas station worker who lost his job returned to the convenience store with a gun and opened fire before killing himself early Sunday in Winston-Salem.

Richard Vance Dixon, 25, was found dead in the parking lot of his former place of work, the Exprezit gas station at 120 Linville Road, shortly after 1:45 a.m.

Alex P. Little, 44, an Exprezit employee and Dixon’s former boss, was found shot multiple times inside the convenience store. Little was in critical condition at Wake Forest Baptist Medical Center as of 8:30 a.m. Monday.

Detectives believe Dixon entered the store armed with a handgun five days after he was fired. Police said Dixon shot his former boss multiple times, then walked out of the store and grabbed a shotgun from his vehicle.

From the parking lot, police said Dixon fired several shotgun blasts into the store before turning the firearm on himself.

Investigators have not said why Dixon was fired. One of the current employees at the gas station said they were shocked to hear about the backlash because Dixon’s firing seemed to be a mutual agreement.

“I mean they’d been working with each other for three years, maybe more. They had a good relationship as far as I know,” Diamond Clinard said.

Clinard, who has worked at the gas station for seven months, said she showed up Sunday morning to open the convenience store.

“I went to go into the store and the cop stopped me. I asked him what was going on and he told me that my boss had been shot and one guy was dead,” Clinard said.

Clinard said both the shooter and victim were her friends.

“They’re both just all-around great people and I can’t imagine what could have been so wrong that Rich would have been out of his right state of mind to do anything this outrageous,” Clinard said. “What has happened is something that I would never expect from him in any way.”

Families of both parties have been notified and the investigation is ongoing, police said.
