Two former female Wisconsin prison officers are being charged with second-degree sexual assault, even though they say the so-called victim -- a prisoner -- seduced them. A year and a half ago, Correction's Secretary Matt Frank said he would enforce a "zero tolerance" policy for sexual contact between prison staff and inmates.

This morning 39-year-old Christine Roberge, a former sergeant and 9-year prison veteran, and 29-year-old Heather Bartosch, who guarded inmates at Oakhill for seven years, will make initial court appearances on the sexual assault charges. At the time of the alleged incidents last year both women were married -- Bartosch to a Fitchburg police detective.

A letter from the inmate that was found by Roberge's husband initiated the prison probe. At first, the warden called the Fitchburg Police Department since Oakhill is in that jurisdiction. But Fitchburg couldn't investigate because one suspect was married to a staff member.

The county investigated and found the inmate seduced the officers at different times into having sexual relations in secluded areas of the prison. According to the complaint, one corrections officer became concerned when he could not find Roberge, who had left her post. He saw her coming out of a towel room with a prisoner.

The other officer was concerned for his own safety, as well as the safety of other correctional officers because he was unsure of what lengths either of them might go to keep it quiet, according to reports.  The prisoner has not been identified since he is a sexual assault victim.
