“Killer Camp”

Bobby Mair is the host.

As they sift through clues, the evidence seems to be pointing the police to an unlikely suspect.
“Insane Pools”
(8 p.m., 11 p.m., DIY): A new episode called “Lake It or Not?” finds Lucas Congdon and his team at Lucas Lagoons undertaking one of the most massive backyard projects of their careers together: a lakeside dream pool and backyard escape that seems to be dedicated to the familiar proposition that everything really is bigger in Texas.
“Court Cam”
(9:01 p.m., 1:04 a.m., AE): Host Dan Abrams introduces a new halfhour assortment of real-life courtroom moments, including a judge who winds up losing his job after his temper gets the best of him.

The terrain around them becomes icier and more treacherous than ever at a time when catching fish becomes more critical to their continuation. One participant finds himself stalked by a pack of deadly predators, so he braces to fight for his very life.
