Michigan authorities say a man working in his yard accidentally killed his wife with a chain saw.

The Otsego couple were trying to cut a tree Sunday when the man hit his wife in the neck with the chain saw.

She died at the scene of the accident, about 35 miles south of Grand Rapids.

Sheriff's Deputy David Labonde lives nearby. He tells WOOD-TV he heard a cry for help and did what he could to help.

The sheriff's department says it's withholding the couple's names until other relatives are notified. The TV station says they're in their 40s.
