LADYSMITH, Wis. -

A Rusk County judge has ruled a man accused of killing his wife is not competent to help with his defense.

That puts the trial for Donald Lazar on hold. The 67-year-old defendant will be held at a treatment facility until mental health officials believe he's able to stand trial.

Lazar is charged with first-degree intentional homicide in the death of 65-year-old Darlene Lazar on Dec. 30 at the couple's home near Hawkins.

The Eau Claire Leader-Telegram reported court records say Lazar admitted fatally shooting his wife after an argument about washing her hands and paying property taxes. Lazar told investigators he didn't realize his rifle was loaded, but shot his wife a second time because he knew he was already in trouble.

The court will get periodic reports of Lazar's progress.
