PICKENS, S.C. - Authorities won't charge a woman who killed her 47-year-old husband last month in their Easley home because he was swinging a knife at her and grabbed a rifle just before he was killed.

Prosecutor Walt Wilkins said Tuesday that the evidence in the case matches the statements from Travis Whitman's wife that she was in fear of her life on March 25.

Wilkins says Whitman and his wife had argued all day after he pleaded guilty to criminal domestic violence charge that morning. Whitman started swinging a knife and threatened to cut her throat. When he grabbed one of the guns, Whitman's wife shot him. The gun was found in Whitman's hand.

Pickens County deputies say they had been called to the home 22 times in the past seven months.
