BANGOR, Maine — Agents with the Maine Drug Enforcement Agency had a local man under surveillance for several weeks for reportedly dealing drugs and caught him earlier this month with a quarter-pound of crack cocaine and hundreds of diverted oxycodone pills.

The street value of the seized drugs is around $60,000, Darrell Crandall, MDEA division commander for northern Maine, said Sunday.

Roger Campbell-Black, 34, of Center Street was arrested May 4 “as he delivered 100 oxycodone tablets and 2 grams of crack cocaine” to someone waiting in the parking lot of a Holden business, Crandall said, who added that Campbell-Black also had $3,000 in cash on him.

Agents then searched his house and seized “over a quarter-pound of crack cocaine, 495 oxycodone tablets and $8,000 in cash,” the MDEA commander said.

After his arrest, MDEA agents learned that Campbell-Black was going to get another delivery of prescription pills from a New York-based supplier the next morning, May 5.

“They staked out the Greyhound bus station in Hampden [and] when Ayanna Johnson, 39, of Brooklyn, N.Y., got off the bus, MDEA agents took her into custody and confiscated 628 more oxycodone tablets,” Crandall said.

The 1,123 pills of oxycodone seized have a street value of around $48,000, and the cocaine is valued at $12,000.

Campbell-Black was charged with felony aggravated trafficking in cocaine and oxycodone, both Class A crimes, and Johnson was charged with felony trafficking in oxycodone, a Class B. Both were taken to the Penobscot County Jail and have since been released, a jail official said.

Campbell-Black faces a penalty of up to 30 years in prison and a $50,000 fine, if convicted, and Johnson could see 10 years behind bars and a fine of $20,000.

The MDEA was assisted by Bangor Police Department, Maine State Police and federal DEA agents and the Maine Office of the Attorney General is handling the prosecution.

“More arrests are likely,” Crandall said. “This case is far from over.”
