PORT ARTHUR, Texas (AP) — Authorities say a man has killed two people before killing himself at a southeast Texas beach.

The Jefferson County sheriff's office says that they got several 911 calls on Sunday afternoon about a shooting in progress at McFaddin Beach.

When deputies arrived they found three people who had been shot to death. The sheriff's office says a man had shot to death another man and a woman and then turned the gun on himself.

Autopsies have been ordered on all three. Their names have not yet been released.

Officials are still investigating the cause of the shooting and the relationship between the victims and the shooter.
