A hero passer-by shot and killed a gunman who ambushed an Arizona state trooper who was helping at the scene of a car crash.
The trooper was helping a woman who had been ejected from a car in a rollover crash when he was brazenly attacked by the suspect.
But a Good Samaritan stepped in and gunned down the assailant in the middle of the road.
Now the Arizona Department of Public Safety are trying to find the hero who intervened, because they believe the trooper may not be alive if it weren’t for her actions.
DPS Director Frank Milsted sent a message out to the Good Samaritan, who he has yet to talk to. He said: ‘Thank you because I don’t know if my trooper would be alive today without your assistance.’
