MISSION, Texas (ValleyCentral) — A murder-suicide is under investigation in the city of Mission.

On Wednesday, officers responded to the parking lot at a hospital in Mission.

When police arrived on the scene they found the two men with gunshot wounds next to a white pickup truck. Both were taken to the emergency room and were pronounced dead.

The preliminary investigation revealed that all three had planned to meet at that location. During the press conference, it was mentioned that the woman worked at the hospital and was on her break.

Mission Police Chief Robert Dominguez said the hospital was put on temporary lockdown as a precaution.

Police also confirmed the woman was the one who reported the incident.

“This young lady basically started a new relationship with this young man and the ex-husband wasn’t too happy with the situation,” said Dominguez.
