Serial rapist released from Minnesota sex offender program

By  | 

ST. PAUL, Minn. (AP) — A three-judge panel has cleared a serial rapist, whose case once triggered a political firestorm, for conditional release from the Minnesota Sex Offender Program, but the Minnesota Department of Human Services said Tuesday that it would appeal.

Thomas R. Duvall, 62, has spent the past 30 years locked up for the violent rapes of teenage girls in the 1970s and 1980s.

In 1987, Duvall bound a Brooklyn Park girl with an electrical cord and raped her repeatedly over several hours while hitting her with a hammer.

The judicial panel on Monday approved Duvall’s provisional discharge, saying his progress in treatment outweighs his “fearful diagnosis” as a sexual sadist, the Star Tribune reported.

At a hearing last April, therapists and other program staffers depicted Duvall as a reformed man who was contrite about his violent history and ready for a return to the community.

But Human Services Commissioner Emily Piper said she’ll try to block his release.

“I, along with three testifying experts in this case, believe that Thomas Duvall poses an exceptional risk to public safety and should not be released into the community at this time,” Piper said. “I disagree with the court’s decision to the contrary and will appeal this decision.”

Under his proposed discharge plan, Duvall will live under intensive 24-hour supervision with GPS monitoring in a facility operated by Zumbro House, which provides community housing to sex offenders in Woodbury, Minnesota, and will not be allowed to leave unless accompanied by staff.
