Weslaco, Texas (KVEO)—Weslaco police department says a man is dead following a possible confrontation with a customer at Walmart Supercenter on North Texas Boulevard.

During a press conference, Weslaco police chief Joel Rivera said a call came in around 3 p.m. in reference to a man with a rifle wearing all black.

“We believe the suspect entered the Walmart through the north side entrance, had a confrontation with a customer and ended up pointing the weapon towards the customer” said, Rivera.

The suspect then headed to the back of the store where he encountered police.

The officers then shot back, killing the man. His identity was not revealed during the press conference.
