ND man, Mann, to plead guilty in drunken driving crash

 A North Dakota man has signed a plea agreement in a drunken driving crash that killed an 84-year-old woman.

Merrill Mann Jr., of New Town, is charged in federal court with involuntary manslaughter. He faces a maximum penalty of eight years in prison.

Authorities say Mann's blood alcohol content was more than twice the legal limit when he caused a crash west of New Town on April 20.

The accident killed Roberta Kiwimagi, who was a passenger in a van that collided with Mann's pickup.

A plea hearing has not been scheduled.
