According to a Goliad County Sheriff's Office report, deputies responded to a call at 11:17 p.m. and found Robert Corbin being tended to by park personnel near the front entrance.
Corbin had puncture wounds and lacerations to both sides of his head, but was coherent and able to talk to deputies.
Corbin said he was staying at one of the campsites and went swimming sometime after 10 p.m. As he was swimming, there was a sudden thrashing in the water and he felt a momentary pressure on his head. He was able to return to shore where he called for assistance.
The alligator swam away in an unknown direction. Corbin said he believes he accidentally brushed the alligator in the darkness while swimming, which caused the animal to react and bite him.
Corbin did not know how big the alligator was and no witnesses to the incident were located.
Corbin was transported to DeTar Hospital by Goliad EMS with non-life-threatening injuries.
Texas Parks and Wildlife game wardens were advised of the incident and are conducting the follow-up investigation.
