According to the sheriff’s office, the deputy was sitting inside a Ford Explorer squad car, parked on the right shoulder, when a single-unit Kenworth truck drove off the road and rear-ended the Ford. It is currently unknown why the truck veered off the roadway.
The deputy was transported to an area hospital with life-threatening injuries and later died, the sheriff’s office said. She was identified as 35-year-old Christina Musil, a five-year veteran of the DeKalb County Sheriff’s Office who served in the Corrections and Patrol Divisions.
