BANGOR – In back-to-back raids, state drug agents seized more than $30,000 in marijuana, illegal mushrooms and other drugs Friday night, arresting three people whom authorities described as substantial drug dealers in the area.

The drug agents, aided by Bangor police and members of the U.S. Attorney’s Violent Crimes Task Force, executed a search warrant at Apt. No. 1 at 52 Market St. and a short time later, at Apt. No. 5 at 36 Essex St.

From the Market Street apartment of Roscoe Sargent, 26, and his girlfriend Heather Fleigelman, 18, authorities seized 11 pounds of marijuana and 3 pounds of psilocybin, or psychedelic mushrooms.

The drugs were stored inside duffel bags and knapsacks, and some were packaged in small plastic bags in preparation for resale, said Garry Higgins, supervisory special agent in Bangor for the Maine Drug Enforcement Agency. The drugs have a street value of about $30,300.

Higgins described the raid as “one of the largest marijuana and psilocybin mushroom busts in a while.”

Also seized was an estimated $1,600 in cash, drug paraphernalia, such as scales, and a loaded 20-gauge shotgun, which officials said was located about seven feet from the drugs. The presence of the loaded gun so close to the drugs prompted investigators to upgrade the charge to aggravated status.

Sargent and Fleigelman were both charged with aggravated trafficking in marijuana and possession of psychedelic mushrooms.

Searching the apartment at 36 Essex St., agents found crack cocaine, methamphetamine, hashish and more than $10,000 in cash, Higgins said. No value for the drugs was available. Police charged the apartment’s resident, Russell Earle, 32, with possession of Schedule W drugs.

All three posted bail, with Sargent being released 12:30 a.m. Saturday and Earle at 4:20 a.m. that same day. Fleigelman was released 10 p.m. Friday.

Sargent had been the focus of an investigation for “an extended period of time,” Higgins said. Authorities also are investigating whether there is a connection among the suspects.

Higgins said police are still investigating both cases and that others could be charged. The marijuana was described as being of “commercial grade” and was brought in from out of state. Authorities seized papers during the raids that contained information about drug deals, Higgins said.

This week, MDEA agents are expected to meet with the U.S. Attorney’s Office to determine whether to pursue federal charges, Higgins said.
