Minnesota gubernatorial candidate Kurt Zellers urged the state's legislative auditor to investigate the destruction of a serial rapist's violent fantasy logs as he vies for his release from the controversial Minnesota Sex Offender Program

On the heels of a Star Tribune report that the state's attorney general alleges a coverup surrounding the potential release of Thomas Duvall, Zellers, a former Republican state House speaker, wrote a letter to Legislative Auditor Jim Nobles urging him to investigate the destruction of Duvall's journals, written as part of his treatment plan.

"What we have seen is a series of either distortions, cover-ups, misinterpretations, or just downright failure," Zellers said Wednesday. "Last February there was a news report that this was some sort of act by Mr. Duvall. Now here we are a few months later, it wasn't Mr. Duvall but someone with DHS destroying these documents."

Nobles ackowledged that he received Zellers' letter but doesn't intend to act.

"This issue is before a state Supreme Court appeals panel and I think that's where it belongs," Nobles said. "The issue was raised by the attorney general, and I think the proper place for this issue to be addressed and resoved is the appeals panel. I don't see a role for my office."

Zellers' comments came after the most recent revelations about the destruction of the logs surrounding the closely-watched and heated debate over whether Duvall can be released from custody. A federal judge urged the state Legislature to take action, but reform efforts went nowhere last session, with both lawmakers and Gov. Dayton urging one another to take action.

Zellers said a "top to bottom" audit is necessary to determine what happened to Duvall's journals, and to address whether he should be released. He blamed Dayton for a lack of leadership on the issue, brushing off criticism that the Legislature failed to act, noting that nothing passed with a House, Senate and governorship under DFL control.

"As governor it starts from the top down," he said. "You can legislate all you want but if your commissioners aren't going to abide by the law or at least the laws that were passed, as a governor it should start and end at the top. If you're not going to do your job then step aside."

Dayton's Deputy Chief of Staff Bob Hume fired back at Zeller's in a statement, blasting Zellers for "political posturing."

"The fact remains that Mr. Duvall is not a prisoner, he is civilly-committed," Hume said. "The decision to destroy his own personal property is between him and his lawyer. Under state statute, which Rep. Zellers helped write and has not mustered the will to change, that is the law."

Nobles' office has previously been involved in audits of MSOP. A 2011 report by the office that showed Minnesota has four times the number of civilly committed sex offenders per capita than 19 other states with similar programs and urged the Legislature to develop a plan for alternate placement for some offenders housed at MSOP along with other reforms.
