The Montgomery County Sheriff’s Office said Deputy Robert Layman and Sgt. Jack Valenzuela were hit early Wednesday morning.

The sheriff’s office said Thursday that the two deputies had assisted a stranded motorist who was in a lane of traffic. As the deputies returned to their patrol car, which was blocking the lane of traffic, a motorist struck them.

Both deputies were taken to a local hospital, where Valenzuela was later released with minor injuries. The sheriff’s office said Thursday that Layman suffered serious injuries and is expected to have a lengthy stay in the hospital.
