SKOWHEGAN – A judge has sealed documents related to drug charges against the girlfriend of a Madison man charged with killing a sheriff’s officer.

Thirty-two-year-old Kristina Pomerleau, 32, of Skowhegan, pleaded not guilty on Wednesday before being returned to the Somerset County Jail. Bail remained at $5,000.

She is charged with unlawful possession of crack cocaine, and with unlawful furnishing of cocaine.

According to police logs, slain Somerset County Cpl. Eugene Cole was involved in the traffic stop April 21 that led to Pomerleau’s arrest. The man charged in Cole’s death, Pomerleau’s boyfriend John Williams, was in the car during the traffic stop.

Williams was charged with killing Cole days later in a late-night encounter.

Pomerleau’s attorney, Philip Mohlor, tells WGME-TV that his client “seems to have peripheral involvement in the situation.” He says the case will likely go to trial.
