DALLAS — A photographer who was attending a wedding in Raleigh on Thursday was shot dead by a gunman, authorities said Friday.

Authorities identified the shooter as 36-year-old Rodeol G. Williams, who had been attending the wedding at the historic Alamo of the Americas in downtown Raleigh, North Carolina.

The shooter was killed by police, police said.

Police said he fled the scene and is now on the run.

Rodeol was a Raleigh photographer for nearly two decades and was the first African-American to be awarded a Pulitzer Prize in photography.

Alyssa K. Davis, who lives in Raleigh, said she was at the wedding and heard screaming from the front of the event and saw the shooter running toward her, a woman who was being treated at a hospital for injuries sustained in the shooting.

Davis told The Associated Press that she saw a man run toward the front door of the wedding venue and that he shot the photographer.

Davis said she heard a second gunshot from the back of the venue and ran toward it.

Davis said Williams, from South Carolina, had been a member of the local NAACP chapter and had a Facebook page that listed him as a member.

The AP has not been able to verify Williams’ claim.

An online profile that was shared by Williams on Thursday described him as “a married, black man from the North Carolina metro area.”

The profile did not identify him by name.

Williams is survived by his wife, Ashley Williams, and two children.

He was born in 1978 in Charlotte, according to the state Department of Commerce.
