Alaska State Troopers have arrested a man charged with murdering his wife, a missing Willow woman found dead this week.

Michael Kilgo, 59, faces charges including first-degree murder and evidence tampering in the death of Hattie Labuff-Kilgo, 56, according to an online dispatch Wednesday.

Kilgo was arrested based on an autopsy on Labuff-Kilgo conducted Wednesday morning, as well as evidence found Tuesday afternoon on Petersville Road along with her body.

“The SME’s office reported to troopers that the manner of death was homicide [caused] by blunt force with sharp force trauma,” troopers wrote.

Alaska State Troopers spokeswoman Megan Peters said Kilgo and Labuff-Kilgo were married. She deferred to charging documents in the case, which weren't immediately available Wednesday afternoon, for further details.

A Monday welfare check by troopers on Labuff-Kilgo after she didn’t show up for work led troopers to continue a search for for her Tuesday. Those efforts turned up her truck about three miles along Petersville Road from the site where her remains were located.

Kilgo was arrested at his Willow home at about noon Wednesday, then remanded to the Mat-Su Pretrial Facility without bail.
