AUGUSTA — A Kennebec County grand jury indicted 10 central Maine residents, and one New York man, on drug trafficking charges.

The indictments, released Thursday, include drug trafficking charges filed against two Waterville residents who were arrested the same day, May 31, following searches which took place simultaneously at three residences, following what police said was a four-month-long investigation into drug trafficking in the Waterville area.

Joshua M. Bilodeau, 27, of Waterville, was indicted on three counts of aggravated trafficking in scheduled drugs, and one count of violation of condition of release, all in Waterville. Bilodeau is alleged to have trafficked in fentanyl powder May 17 and May 29, and cocaine base May 29, with each sale allegedly taking place within 1,000 feet of a school. He was arrested following a search of a Summer Street, Waterville, apartment.

Arrested following that same investigation, after police searched a Gray Avenue, Waterville apartment, was Christopher Violette, 41, of Waterville. He was indicted on two counts of aggravated trafficking in scheduled drugs, fentanyl, Jan. 29 and Feb. 28 in Waterville.
