A man was sentenced Monday to four years in prison in connection with one of the worst-ever cases of police corruption in Maine.

Jeffrey Bishop, 55, was a police officer in Calais and once ran for sheriff in Washington County.

According to the Bangor Daily News, Bishop originally faced 35 charges, but pleaded guilty in August to 14 felony charges as part of a deal with state attorney general’s office.

Investigators said Bishop was caught giving opioid pills to a teenage girl in a high school parking lot in Harrington.

Police said the drugs were intended for the girl’s mother, as Bishop sometimes traded drugs for sex with the mom.

Police also said they found more than a dozen stolen guns at his home in Cherryfield.
