A Pennsylvania state police trooper who was shot in a 2014 ambush has had his right leg amputated below the knee.
Trooper Alex Douglass underwent the surgery this week at a New York City hospital.
His friend Earl Granville says Douglass had some medical complications with his leg and decided to amputate it to improve his quality of life.
Granvillle, a veteran who lost his leg in Afghanistan, says he and Douglass completed the New York City Marathon handcycle event in 2015. He says Douglass should be able to run marathons now with a prosthetic.
