A few hours after being fired, a Texas man returned and began shooting at his former coworkers, CNN reports. He killed one before shooting himself.
The man, whose name has not yet been released, worked at Knight Transportation in Katy, Texas. It is believed that the dead victim was his supervisor, though his identity is also being kept private.
One other person was injured and treated at the location, while a sheriff's deputy received a knee injury and was taken to a hospital.
