A deputy with the Canadian County (OK) Sheriff's Office was killed in a two-vehicle collision on Friday.
The agency said on Facebook, "It is with a very heavy heart that I request prayerful support for our Canadian County Sheriff’s Office family at the loss of Lt. Shirley Lanning. Shirley was suddenly taken from us this morning in a car crash while on duty."
The agency said that Lanning was loved very much by all who knew and worked with her, and she will be dearly missed.
The post concluded, "Shirley was a dedicated and committed law enforcement professional. She previously worked for the Oklahoma County Sheriff's Office and then retired from the University of Central Oklahoma campus police before coming to work with us here at CCSO."
According to Oklahoma City police, preliminary investigation shows that Lanning was westbound on Northwest Expressway, and the other vehicle was eastbound. Lanning’s vehicle entered into oncoming traffic for an unknown reason, police said. The driver of the other vehicle involved tried to avoid the collision, but was blocked by another vehicle traveling alongside them, reports KOCO.
Police said the vehicles then collided head-on.
Lanning was extricated from her vehicle and taken to a local hospital, where she was pronounced dead.
Two people in the other vehicle suffered non-life-threatening injuries, according to reports.
