ST. LOUIS COUNTY – A local pharmacist has been arrested and charged with stealing a controlled substance.

St. Louis County police say a Jennings officer working a hot spot policing detail Oct. 7 in the 9200 block of Halls Ferry Road because the department had received numerous complaints about drug activity in the area.

The officer started to run license plates of vehicles parked on the Walgreens parking lot when he identified a vehicle belonging to a suspect wanted for questioning in thefts of prescription drugs from a nursing home in south St. Louis County. The officer spotted the suspect walking in the store, so he followed him.

The suspect, identified as 35-year-old Clintin Z. Ross, of Godfrey, Ill., was working as a pharmacist at the store. He was arrested on the outstanding warrant and was illegally in possession of hydrocodone pills at the time of the arrest.

Police say a search of Ross' cell phone showed he had conversations with local body builders about selling stolen human growth hormone. The HGH case remains under investigation.

According to police, Walgreens cooperated with officers and an audit revealed missing quantities of hydrocodone and HGH.

Ross is accused of stealing prescription painkillers while working as a pharmacist at a nursing home. He was fired from that job before he was hired by Walgreens.
