The Oklahoma Highway Patrol's dive team spent the day at Keystone Lake trying to help a teenager find his prosthetic leg.
Brendon Wiseley lost his brand new prosthetic leg while tubing on Keystone Lake over Memorial Day weekend.
The leg is made of carbon fiber and titanium so it sank right away.
Monday was one of the OHP's Underwater Search and Recovery Team regular training days, so they used it to help look for the prosthetic.
"It's incredibly relevant and accurate training scenario for a small item search, such as a weapon or something like that, evidence from a crime, the kind of calls we might get. So it's excellent training, and, hopefully, in the process of getting some good training we can take care of a young man who was out having a good time and lost his prosthetic," Lieutenant Jeff James said.
The Tulsa County dive team has also searched twice for the leg.
