A month-long investigation by the Madison County Sheriff's Office into the alleged sale of cocaine ended with the arrest of a Bridgeport man.

Shawn Boysen, 22, was arrested yesterday morning while in Madison County Court on an unrelated charge.

Boysen faces two felony counts each of Criminal Possession and Criminal Sale of a Controlled Substance. If convicted, he could serve between five and 25 years in State prison and pay up to $30,000 per count.
