Bull shark remains reportedly found in lake off Trinity River in Liberty County

A Liberty County man claims he found the decomposing remains of a bull shark in Twin Lakes in Kenefick Tuesday.

Jared Moser, 25, says he came across the nearly 5-foot-long shark while riding his four-wheeler along the riverbank.

"I just rode up on it and couldn't believe what I was seeing," Moser said. "My whole life I've heard that sharks can be found in the Trinity River. I am a true believer now."

Moser suspects the shark swam up the Trinity River and became stranded in Twin Lakes when river levels dropped.

After he found the shark, Moser took a few photos and posted them on Snapchat "for all the people who don't believe me that there are sharks in the water," he said. "That's why I don't swim in the Trinity."

Late Tuesday afternoon, Moser said he returned with a friend to look at the shark again.

"My friend likes to swim in the river. I've been telling him it's not safe and I wanted him to see this for himself," he said.

Texas Game Warden Randy Button, who learned about the shark late Tuesday, said he is skeptical that the shark swam up the river and became stranded in the lake. He believes it is more likely that the shark was dumped by a fisherman.

"The only time the river has been high enough to flood that area was last year. That is a long, long time for a shark to survive in freshwater," Button said. "Bull sharks will go upriver but I personally haven't seen a shark up that far. It's really weird."

Moser had the same suspicions as Button initially but says there is no sign of trauma to the shark and says the area is remote and hard to access by vehicle or boat.

"There were no gunshot wounds and no fins cut off. I couldn't find any tire marks or footprints in the area either," Moser said. "It looks like it just swam up there and died."

In 2006, two fishermen caught a 5-foot-long bull shark below the Lake Livingston Dam, some 40 miles further north up the Trinity River. In that case, game wardens also suspected that the shark was dumped by a fisherman but it was never proven.

Button and Moser plan to go to the site early Wednesday morning for a closer inspection of the shark. The Dayton News will follow up if information warrants an update.
