Three Tisbury residents are facing charges after police in Tisbury and Falmouth worked with members of the Cape Cod Drug Task Force and the U.S. Drug Enforcement Administration on a two-month investigation into drug distribution on the Island, according to an announcement from the Tisbury police.

At about 10:30 p.m. in Falmouth Tuesday, members of all four agencies executed a search warrant on a vehicle registered to Janelle Berneche, 31, of Tisbury, police said. Jason Mello, 32, of Tisbury, was with Ms. Berneche in the vehicle.

Following the vehicle search, both were arrested for possession of a Class A substance suspected to be fentanyl, according to police.
