An 11th suspect was arrested Wednesday afternoon on drug charges resulting from a yearlong investigation by the federal Drug Enforcement Administration and the Warren County Sheriff’s Department.

Chasty Moore, 22, 1245 Mount Alban Road, Lot 6, was nabbed just after 1 p.m., said Sheriff Martin Pace, joining 10 other Warren County residents rounded up earlier in the day who face a number of charges related to fraudulent acquisition and distribution of prescription medications.

Moore was charged with one count of sale of Xanax and one count of conspiracy to distribute a controlled substance, said Pace. Her bond was set at $9,000 — $7,500 for the sale charge and $1,500 on the conspiracy. She remained in the Warren County Jail this morning awaiting an initial hearing in justice court.

Others arrested Wednesday face charges related to oxycodone and hydrocodone, both classified as Schedule II or III controlled medications under the Controlled Substances Act. Xanax is a Schedule IV drug.

Pace said illegally diverting, using and selling prescription drugs is outpacing the use of methamphetamine and cocaine.

“It’s the fastest-growing drug problem we have,” Pace said Wednesday. The drugs are readily available and highly addictive, he said.

Justice Court Judge Jeff Crevitt set bond for all defendants based on affidavits, not personal appearances by the 11, the sheriff said. Bond was set at $7,500 per count for sale charges and $2,000 for each count of fraudulent acquisition.

“We do expect more arrests to be made,” Pace said this morning, but he would not say how many and would not speculate on when they would be made.

• Colum Woodson, 32, 2625 Alma St. — five counts of obtaining controlled substance by fraud; $10,000
