Lt. Col. John Butler is serving as interim commander of the Wyoming Highway Patrol following the retirement of Col. Jess Oyler on Dec. 31.
"During this interim time, the WHP will be in very capable hands with Lt. Col. Butler, with no change in continuity of their operation," WYDOT Director John Cox said in announcing the appointment.
Butler, a 27-year Patrol veteran, has served as the Patrol's operations commander since July 2010.
He joined the Patrol as a recruit patrolman in 1985 and was initially posted in Lander. He was promoted in 1998 to Division A supervisor in Cheyenne.
In 2003, he assumed duties as commander of Highway Patrol District 1, which encompasses Albany, Laramie and Carbon counties. Beginning in 2005, he held the rank of major, serving as field commander.
A native of Douglas, Butler is a 1978 graduate of Sheridan High School, and he subsequently attended the University of Wyoming.
