GASTONIA, N.C. -- The Gastonia Police Department arrested a man in connection to a deadly shooting outside a plasma donation center on Thursday morning.

Police responded to a shooting around 9:45 a.m. Thursday in the 500 block of North New Hope Road. The shooting occurred at a plasma center.

Adrian Martel Curry, 28, was charged with first degree murder after detectives said he shot Demetrius Terrell Wheeling, 39, in the KEDPlasma Center parking lot off North New Hope Road.

Ronnie Suggs was at the plasma center working a plumbing job when he said he watched Curry, Wheeling and another man get into an argument. "The shooter, next thing I know, he said, 'I got something for you' "He lifted up his hand and shot the guy," said Suggs.

Wheeling was transported to CaroMont Regional Medical Center, where he later died. Police said both Curry and Wheeling knew each other prior to the shooting.

"It just hurts that you can't even go to donate at a plasma center without being a victim," said Trinity Millan who frequently goes to the plasma center and said she's shocked by the crime.

Late Thursday, Curry turned himself in to Gaston County deputies outside of the jail; only NBC Charlotte's cameras were rolling when Curry was arrested.

Curry is expected to have a first appearance in court Friday afternoon.
