A Mount Shasta city councilwoman is among 33 people arrested in a four-month investigation into drug sales at two area high schools.

The Siskiyou County Interagency Task Force says an undercover agent enrolled at different times as a student at Yreka and Mount Shasta high schools to track illegal drug sales.

Jim Parker, a senior special agent in charge at the California Department of Justice, says agents received several tips that 40-year-old Katrina Howard was involved as a seller.

Howard, a city council member since November, had 34 pounds of processed marijuana in her home, according to the task force.

She was arraigned Friday in Siskiyou County Superior Court on charges of conspiracy to sell marijuana and maintaining a residence where marijuana is stored or sold. Howard did not yet have an attorney and was being held in the Siskiyou County Jail.
