An unlicensed rehab center manager has been arrested in Prescott for drug sales. Members of Yavapai County’s Partner’s Against Narcotics Trafficking Taskforce executed a search warrant last week at the Roundsville Treatment Center in the 600 block of North Bagby Drive in Prescott. Detectives found evidence of drug sales at the facility, involving LSD and marijuana. Authorities also found mushrooms and a short-barreled rifle with no apparent serial number on it. Nine people were detained, including 22-year-old Clayton Yost. Detectives linked the drug sales to Yost and he was booked on numerous drug charges. Yost was on probation for several drug charges in 2018. He remains in the Camp Verde Detention Center on $35-thousand dollars bond.
