The shooting death of a Huntsville man at an Alabama Waffle House remains under investigation.

Cristall Terrell Hereford, 26, was killed early Sunday at the restaurant on Center Point Parkway.

Jefferson County sheriff’s Lt. Joni Money said deputies were dispatched at 1:30 a.m. to the restaurant on a report a person was threatening to shoot patrons.

Before deputies got on the scene, Money said, Hereford got into an altercation with another patron. The patron then shot Hereford and left the location.

Hereford was pronounced dead on the scene at 1:48 a.m.

Video posted to social media showed Hereford unresponsive on the ground just feet from the building after he was shot, with at least one bystander trying to help him and calling 911.

Another bystander could be heard saying, “Out here trying to be tough and he got killed.”

Money said no weapon was recovered from Hereford at the scene.

In the hours leading up to the deadly shooting, Hereford had posted this on Facebook: “Omw to Birmingham with that drac on me, Yall pray for me.”

Money said investigators were able to track down the shooter on Monday. He was detained briefly for questioning and then released pending the course of action to be determined by the Jefferson County District Attorney’s Office.

The District Attorney has “not yet determined the charging decision,” according to a press release.
