this is from deputy tyler milton's car. up ahead is the car that he's been pursuing. behind the wheel, 36-year-old justin derby, the pursuit not very fast at first but it quickly gets up to speeds of 117 miles per hour. up ahead, he's trying to pass a tractor-trailer and -- >> oh! >> rollover. >> almost goes head-on into another truck, swerves to the right. the car goes off into the field. but inside the car was not just mr. derby. he had four passengers. there goes mr. derby off on foot. now here's where it gets more interesting. because deputy milton is wearing a body camera. the pursuit continues through the field. the foot pursuit slows down because mr. derby jumps into a pond. deputy milton now draws his weapon. >> get out and on the ground. >> mr. derby with a gun on him refuses to come out of of the pond. wait, check that, that's not a pond, per se. it's a sewage treatment pool. >> okay, this situation just went from bad to even worse. >> he's going nowhere and tries to stave off his arrest for as long as he can before the pool gets too cold for him to stay in
