WILSON, N.C. (WNCN/AP) — A pregnant U.S. Navy veteran was shot to death at a music hall in Wilson County Sunday morning, authorities said.

Precious Vernetta Dyer, 29, was shot during a fight at a Christmas event, but the sheriff’s office said she was a bystander and that there was no evidence of her being directly involved in the altercation.

Deputies found Dyer shot after responding about 1:30 a.m. Sunday to a “shots fired” call at Evolution Music Hall, located at 4610 Highway 301 South.

Her mother, Tijuana Locus, told WRAL-TV she saw on Facebook that there was a shooting at the event and began frantically messaging her daughter. The sheriff’s office later called to inform her that Dyer died. Locus said she thinks her daughter was caught in the crossfire.

“It’s been terrible,” she said. “For me, I know that Christmas will never be the same.”

Dyer served in the Navy for seven years and was four months pregnant, according to the station. She planned to marry the father of her baby in January.

The case is still under investigation, and officials said no further information will be released at this time. It is expected to be a lengthy investigation because of the large number of people at the event.

Anyone with information is asked to call the sheriff’s office at 252-237-2118.
