An Avondale man is scheduled to be arraigned on charges in the shooting death of a rookie state trooper during a roadside struggle on Interstate 10.
Isaac Damon King is expected to enter a plea Thursday on murder and other charges in the July 25 shooting death of 24-year-old Trooper Tyler Edenhofer.
Authorities say officers were struggling with King for several minutes when he somehow got hold of another trooper's gun and fired two shots.
The shots killed Edenhofer and wounded another trooper in the shoulder.
The struggle came after troopers responded to a call that a person was throwing rocks at vehicles on the interstate.
Authorities say King was on medication for anxiety and depression.
Edenhofer was killed just two months after graduating from the Department of Public Safety academy.
