Texas Parks & Wildlife Department Lt. Billy Champlin said Thursday that two people who were fishing called an agency hotline to report they euthanized the gator.

Champlin says the callers said they were fishing for catfish with a drop line when the alligator got hung up on a hook, and they had to put the gator down. The callers Wednesday led a game warden to the carcass above Stillhouse Hollow Reservoir, near Harker Heights.

Champlin did not say how the alligator was killed. The carcass was retrieved as evidence.

Alligator hunters must be licensed, have the landowner’s permission and secure a tag purchased upon harvest of the animal. Alligator hunting season runs April through June.
