PORTLAND, Ore. — The wife of a chef fatally shot in June in the Portland, Oregon, culinary school where he was a lead instructor has been arrested on suspicion of killing her spouse.

The Oregonian/OregonLive reports 68-year-old Nancy L. Crampton-Brophy was arrested Wednesday and booked into a jail on accusations of murder and unlawful use of a firearm.
