A man was shot and killed in a Grand Prairie office building.
The shooting happened Tuesday afternoon, in a building in the 2000 block of North Highway 360. Police believe the suspect and victim were Crescent Processing Company co-workers.
A witness said the victim was shot in the head. He was transported to the hospital, where he died.
The gunman left the building, but was taken into custody three hours later. He is being held on murder charges.
No names have been released.
Concordia University Texas, which is also located in the building, announced it would relocate classes to the Hyatt Place hotel Tuesday evening for the safety and protection of students, staff and faculty.
