The Anchorage Police Department wants help in finding two witnesses to a serious traffic accident on Sunday that may have helped save an injured man's life.

Israel Hale, 25, was driving near the Salvation Army on Dimond Boulevard around 5 p.m. when a trailer he was towing broke down, according to a statement from police Monday. He had gotten out of the truck to deal with the problem when a 17-year-old driver hit Hale, pinning him between her vehicle and the trailer.

Hale's legs were severely injured and bleeding heavily, according to police. A woman on the scene who said she was a nurse stopped and began applying tourniquets. Another man wearing a green shirt helped. Neither gave their names. The two left the scene of the accident before officers could ask for their names.

"Officers on scene credit the actions of these two citizens with saving the life of the accident victim," the APD said in its statemen.

Hale was taken to an Anchorage hospital, where he is being treated for his injuries.
