Michigan ? Wearing neither coat nor shoes, a fugitive suspected of killing and dismembering his wife was found hiding under a fallen tree Sunday in a snowbound state park after a bitterly cold night on the run, authorities said.

Police tracked down Stephen Grant about 225 miles north of the suburban Detroit community where body parts believed to be those of his wife were discovered. He was in stable condition and was being treated for frostbite and hypothermia under police guard at a hospital.

Grant was wearing only slacks, a shirt and socks when he was captured nearly 10 hours after he abandoned a truck and set out on foot in Wilderness State Park near the tip of Michigan’s Lower Peninsula, Emmet County Sheriff Pete Wallin said. He had no weapons and did not resist.

“I don’t think he probably could have made it much longer in those kind of conditions,” Wallin said during a news conference.

Grant, 37, will be returned to Macomb County for arraignment in the death of Tara Lynn Grant, a 34-year-old businesswoman and mother of two who disappeared last month. A torso found in the family home and other body parts found in a park near their home were believed to be hers.
