FAIRFIELD — Authorities discovered evidence of illegal drug trafficking activity Tuesday afternoon during a search of a rental unit at The New American Lodge, resulting in the arrest of 22-year-old Marissa Grover.

The Somerset County Sheriff’s Office Criminal Division executed a drug search warrant following a monthslong investigation at the residence, Sheriff Dale P. Lancaster said in a news release.

Officers discovered and seized approximately 24 grams of fentanyl, crack cocaine and methamphetamine, $231 in suspected illegal drug proceeds and other illegal drug documentation and paraphernalia.

A total of 10 officers and detectives from the Somerset County Sheriff’s Office and Waterville and Fairfield police departments executed the search warrant.

Grover was charged with aggravated trafficking in scheduled drugs, which is a Class A felony. Class A crimes are punishable by up to a 30-year incarceration and a $50,000 fine. She is on probation for a 2024 conviction for unlawful trafficking in scheduled drugs in Kennebec County. Her probation officer placed a probation violation hold on Grover, whose bail was initially set at $25,000 cash.

The case was reviewed by the Somerset County District Attorney’s Office, which filed a complaint with the court and charged Grover with two counts of aggravated trafficking in scheduled drugs, two counts of aggravated furnishing in scheduled drugs and two counts of furnishing scheduled drugs.

Following her initial court appearance Wednesday at the Somerset County Unified Criminal Court, the judge reduced Grover’s bail to $10,000 cash.

She is being held without bail on the probation violation hold.
