Son of Pinal County sheriff arrested in 2020 injury crash

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.

Asked about the allegations, John Schill, an attorney for Cooper Lamb, said he was innocent until proven guilty.

The sheriff did not immediately respond to a request for comment.
