PHOENIX (AP) — The 20-year-old son of Pinal County Sheriff Mark Lamb has been arrested after toxicology tests showed he was impaired at the time of a 2020 crash in which a bicyclist was severely injured, authorities said.
Cooper Lamb was booked into a Maricopa County jail late Wednesday on suspicion of aggravated assault and possession of dangerous drugs, said Sgt. Joaquin Enriquez, a Maricopa County Sheriff's Office spokesman.
Mark Lamb had asked the Maricopa County Sheriff's Office to take over the investigation into the July 8 crash in the San Tan Valley area.
Cooper Lamb is accused of smashing into a bicyclist after veering off the road.
Online court records don't list an attorney for Cooper Lamb who could comment on his behalf, and the sheriff did not immediately respond to a request for comment.
