38-year-old Denise Prell is accused of having an inappropriate relationship with an inmate.

Prell is charged with first-degree promoting prison contraband, 23 counts of official misconduct, and third-degree sexual abuse.

Police say the investigation is continuing and additional charges are anticipated.

Investigators say the 38-year-old was sacked from her civilian job at the maximum-security prison in Dannemora after a guard caught her engaged in inappropriate behavior with an inmate.

New information on the former correctional facility employee facing charges following a multi-agency investigation. Prell has since been fired.

Prell is scheduled to reappear in the Town of Beekmantown Court on October 18, 2017 at 5:00 p.m.

Police said she was being held for lack of $10,000 cash or $25,000 bond.

According to a media release, the Department of Corrections and Community Supervision initiated the investigation after a correction officer observed inappropriate behavior between Prell and an inmate; Prell was subsequently terminated. The incident took place at the Clinton Correctional Facility in upstate NY, the same facility where prison seamstress Joyce Mitchell aided convicted murderers Richard Matt and David Sweat in their escape from prison two years ago.

The high-profile prison break is the subject of the upcoming Showtime miniseries Escape at Dannemora, directed by Ben Stiller and starring Academy Award winners Patricia Arquette as Mitchell and Benicio Del Toro as Richard Matt.

“This case illustrates the cultural shift that has occurred at the Clinton Correctional Facility due in large measure to the changes in policy, procedures and training programs implemented following the Inspector General’s report”.
