BLISS TOWNSHIP, Mich. – Stumbling shoeless and frozen through hip-deep drifts, Stephen Grant finally collapsed in exhaustion early Sunday, bringing his wild run from police to an end in Michigan’s snowy north woods.

Deputies ringed him as a bright orange Coast Guard helicopter hovered.

For 10 hours, Grant had plowed on foot through Wilderness State Park at the tip of the Michigan Mitten with a posse of county, state, federal and Indian tribal lawmen with tracking dogs on his trail. From their helicopter above the woods, Coast Guardsmen and an Emmet County sheriff’s deputy used night vision goggles to pick up Grant’s path and help direct the searchers below.

On Sunday morning, Macomb County Sheriff Mark Hackel stood up at a news conference to announce Grant’s arrest.

“So our No. 1 suspect, the only suspect, is now in custody for the murder and dismemberment of his wife, Tara Grant,” Hackel said on live television.

The end came quietly.

“I think his physical condition prevented him from getting into any confrontation,” Hackel said.

Hackel said investigators spoke with Grant after his capture, and ” some things … came out.”

“We think we have the right man based on some of his statements,” he said.

Investigators say that after Grant killed his wife – an international business executive and mother of their two young children – he cut up her body and scattered pieces around Stony Creek Metropark near their Washington Township home. The park was one of their favored family spots. Deputies found her torso Friday, wrapped in trash bags inside the garage.

“What he had done to her, I think, is one of those things people could imagine in some kind of movie,” Hackel said.

Macomb County Prosecutor Eric Smith said Sunday authorities are still trying to determine when Grant will be arraigned on charges of open murder and mutilating a corpse, but a Tuesday court appearance is possible. Grant is expected to be hospitalized at least until Monday.

Dr. John Bedner, chief of staff and medical director for the Northern Michigan Hospital in Petoskey, treated Grant for frostbite on his extremities and hypothermia.

When Grant arrived, he was in serious condition, and doctors had to work to warm up his core temperature, said Barbara Allen, a hospital spokeswoman. He was later upgraded to stable condition.

Late Sunday, Grant remained in the intensive care unit – typical for his type of injuries – and was to be observed at least overnight. Like burns, severe frostbite often doesn’t show symptoms for at least 24 hours, Allen said.

“He is awake, alert and cooperative with hospital staff, and has been from the time he arrived,” she said.

Two Macomb County Sheriff’s deputies arrived Sunday morning to guard Grant.

On Friday, detectives equipped with a long-anticipated search warrant uncovered grim evidence in the couple’s Washington Township garage, three weeks after the mother of two young children vanished: what they believed to be Tara Grant’s torso.

A search party equipped with all-terrain vehicles and cadaver-sniffing dogs collected most of her other body parts Saturday in a little less than a mile of wooded land behind Stony Creek.

A smaller group of reserve deputies combed the area again Sunday before ending the endeavor in the late afternoon. As a result, they tracked down the rest of her remains.

“The nature of this crime – a murder followed by dismemberment and disposing of remains – may hold up as premeditation in court, said Smith, the Macomb County prosecutor.

“The way he went about this crime, it suggests he had a plan.”
