MADISON — Three people from Massachusetts and a Madison woman were arrested on drug charges Wednesday after investigators executed a search warrant at a Madison residence, according to the Somerset County Sheriff’s Office.

A team of detectives and deputies executed a search warrant at approximately 5:30 a.m. at an Ingalls Street residence, Sheriff Dale Lancaster said in a statement issued Thursday afternoon.

The Sheriff’s Office criminal division obtained the warrant after a month-long investigation that indicated “illicit drugs were reportedly being sold from the residence,” according to the statement.

Investigators seized more than 25 grams of cocaine and fentanyl, controlled pills, Suboxone strips, drug-related documentation and items and digital scales, Lancaster said.

Kevin Pimentel, 36, of New Bedford, Massachusetts; Shaina Andrade, 40, of New Bedford, Massachusetts; and Clifford Colby, 65, of Bourne, Massachusetts, were each arrested on one Class A count of aggravated trafficking in scheduled drugs and one Class B count of unlawful trafficking in scheduled drugs, Lancaster said. The aggravated trafficking count was due to the amount of fentanyl seized, according to the statement.

Pimentel was also arrested as a fugitive from justice, as there was a warrant for his arrest in Massachusetts for trafficking in heroin, Lancaster said.

Also arrested was Roxanne Cormier, 59, of Madison, on one Class C count of unlawful possession of scheduled drugs, Lancaster said. Cormier is also being held for violating terms of probation.

All four were being held at the Somerset County Jail in Madison as of Thursday afternoon.

Pimentel was being held without bail, Andrade and Colby were each being held on $10,000 cash bail, and Cormier’s bail for the drug charge was set at $500 cash.

If any of those arrested remain in custody Friday they would be expected to appear before a judge in Skowhegan Friday afternoon, when bail may be changed and attorneys would be appointed if necessary.

All four are due back in court in Skowhegan June 4, according to Lancaster. The Somerset County district attorney’s office is reviewing the case.
