AUGUSTA — Four people were arrested Monday on drug charges after city police say they searched a residence on Page Street and seized packaged heroin and cocaine.

Augusta police executed a search warrant at 2:45 p.m. at the building, where more than 18 grams of heroin packaged for sale and 4 grams of crack cocaine were found by authorities, according to a news release Tuesday from Deputy Chief Jared Mills. A Maine State Police dog assisted with the search of the residence as well as a Kennebec County Sheriff’s deputy, according to Mills.

Following the search, police arrested Scott Holbrook, 53, of Augusta; Desiree Mckenna, 25, of Augusta; Isidore Holmes, 25, of Brooklyn, New York; and an unidentified 17-year-old girl from Rockaway, New York.

Holbrook, McKenna and Holmes were each charged with two counts of trafficking in scheduled drugs. Holbrook’s bail was set at $15,000 cash, McKenna’s at $5,000 cash, and Holmes at $25,000 cash. All three were being held Tuesday at the Kennebec County jail in Augusta.

The 17-year-old was being held at an unidentified juvenile correctional facility, according to Mills.

The warrant was executed by the Augusta Police Department’s Special Response Team and resulted from a joint investigation with the Maine Drug Enforcement Agency.
