AUGUSTA, Maine — Four of the 10 people arrested in December and charged with dealing heroin have been indicted by the Kennebec County grand jury for aggravated trafficking in the street drug.

Peter Gleason, 32, of Augusta; Ricquell Lindo, 20, of Stroudsbury, Pa.; Tyshawn Mack, 22, of Bath, Pa.; and Nathaniel Taylor, 19, of New York City all were indicted Friday for Class A aggravated trafficking in scheduled drugs.

The four are accused of trafficking in heroin “in a quantity of 6 grams or more or 270 or more individual bags, folds, packages, envelopes or containers of any kinds containing heroin,” the court documents state.

A Class A charge carries a penalty of up to 30 years in prison and a maximum fine of $50,000.

The 10 people were arrested after a Dec. 19 raid on a Penly Street residence by Augusta Police Department’s Special Response Team and members of the Maine Drug Enforcement Agency, Kennebec County Sheriff’s Office, Maine State Police and U.S. Drug Enforcement Administration. The bust resulted in officers seizing 45 grams of heroin and approximately five grams of a substance believed to be methamphetamine, according to the MDEA.

The heroin has an estimated street value of $10,000.

Tyrone Wilkins, 23; Darvent Cummings, 22; Kenya Evans, 20 — all from Stroudsburg, Pa.; Shaquanna Khaleelah, 18, of Mt. Pocono, Pa.; and a 17-year-old female, who was not named by police, also were charged in December with trafficking heroin and conspiracy to traffic in scheduled drugs.

Ryan Minoty, 21, of Augusta was charged with unlawful possession of Schedule W drugs and unlawful possession of drug paraphernalia.

Some of the 10 arrested in December are members or affiliates of a violent street gang known as the Almighty Black P. Stones, according to information provided by the MDEA that does not list the gang members by name.
