Corporal Edstrom was wounded on September 19, 1959, during a gun battle with three fugitives from New Mexico. The fleeing car crashed through a Durango roadblock on US Highway 550. The chase was terminated when the wanted car went down a dead-end alley. The driver and a passenger jumped out with their hands up. However, a second passenger ran and Edstrom stopped him as he tried to get into another car. During the ensuing gun battle, Edstrom was hit twice. Assisting officers from the Durango Police Department opened fire, hitting the suspect five times. He died instantly. Edstrom was hospitalized at Mercy Hospital in Durango and died on October 28, 1959.
Edstrom entered the Patrol May 21, 1951.
