WINTERPORT, Maine — A tip about suspected heroin dealing in the parking lot of a village convenience store on Sunday led to drug trafficking charges against a Hyde Park, New York, woman, according to police.

Amanda Crain, 30, was charged with unlawful trafficking in scheduled drugs, a Class B felony crime, after she was found in possession of 4 grams of heroin and $321 in suspected drug sales proceeds, Chief Deputy Jason Trundy of the Waldo County Sheriff’s Office said in a press release Monday.

A Class B crime is punishable by up to 10 years in prison and up to a $20,000 fine.

Cpl. Merl Reed, Deputy James Porter and MDEA agents “coordinated together on information that Ms. Crain was in the area attempting to sell heroin,” Trundy reported.

Crain was located in the parking lot of the Foster’s Winterport On the Run convenience store. A store manager said Monday that employees were unaware of the situation until the sheriff’s department showed up and took the woman away.

Crain was arrested Sunday and taken to the Waldo County Correctional Center, where bail was set at $10,000 cash, Trundy said.

She remained behind bars Monday night, a jail official said.
