ERIE — A 25-year-old Erie man is facing drug charges after Pennsylvania State Police (PSP) executed a narcotics search warrant at a West Erie address last week, authorities announced in a press release.

Marcus Laquincy Poston Jr. was taken into custody on May 6 after troopers from PSP Troop E Vice Unit, working alongside the Millcreek Township Police Department, Erie City Police Department, Pennsylvania Office of Attorney General and Erie County Detectives, raided a residence at 1345 W. 32nd St. in Erie.

During the search, officers discovered a large quantity of suspected fentanyl, methamphetamine and United States currency in Poston’s possession.

The arrest, however, revealed a broader criminal operation. Investigators determined that Poston had allegedly conspired with five other individuals to bring large quantities of fentanyl and other narcotics to the Erie area. Those named in the conspiracy include Michael Gaines, 51, of Erie; Jamaand Greenwood, 43, of Chicago Heights, Ill.; Chanel Sherman, 32, of Chicago Heights; DaJuan Willingham, 28, of Chicago, Il.; and Leon Tuner, 25, of Chicago Heights.

Poston has been charged with manufacture, delivery, and possession with intent to manufacture or deliver a controlled substance, along with related offenses. The investigation remains ongoing.

Authorities note that information is preliminary and subject to change as additional investigative details emerge.
