One of the convicted ring-leaders in the Portage House-of-Horrors case now says he was mentally exhausted when he admitted to some of the crimes and he wants to plead innocent.

A Columbia County judge is expected to decide tomorrow whether Michael Sisk, 26, can withdraw his earlier pleas to 10 charges. He struck a plea deal in August for the killing of Tammie Garlin and the torturing of her 12-year-old son.

They occurred at a house in Portage where Sisk, Garlin and others had lived for a few months before the crimes were discovered in June of 2007.

According to court records, Sisk thought his pleas would spare him from life in prison but he now knows he could serve what amounts to be a life term. And he said he was pressured into accepting it.

Sisk entered an Alford plea to reckless homicide, and guilty to hiding a corpse, false imprisonment, and mayhem among other things.

Sisk is still scheduled to be sentenced on those charges Dec. 30.
