'My 600-lb Life' star L.B. Bonner found dead

James "L.B." Bonner, who appeared on the TLC reality series My 600-lb Life, has died. He was 30.

Police in South Carolina found Bonner dead in a park on Thursday evening, TMZ reported. He had a gunshot wound.

The police department, which is investigating, did not immediately return Fox News' request for comment.

TLC posted a statement on its website confirmed Bonner's death and said the network was "deeply saddened and was "honored to have shared his honest and courageous story."

"On the show, viewers saw LB struggle with obesity following a tragic accident that claimed his right leg. Even though he once weighed 650 pounds, LB's hard work and dedication helped get him in the 200-pound range," the statement said. "His spirit and determination as displayed through his story, quickly made LB a fan-favorite…"

In a message posted Thursday evening to a Facebook community page that bears his name, Bonner purportedly thanked people for showing him "love and support" in his journey.

"I've realized a few things over the last few days and its time that, I face my demons head on," the post said.

Police have not released a cause of death. But TMZ reported that investigators are not looking for any suspects, indicating that Bonner may have died by suicide.
