National Briefing | South: South Carolina: Man Found Incompetent for Trial

Prosecutors said they wanted a 78-year-old man committed to a mental hospital after he was found incompetent to stand trial in the 2003 killings of two South Carolina law enforcement officers. The announcement by Solicitor Jerry Peace came a day after a circuit judge ruled that the man, Arthur Bixby, could not stand trial because he had dementia. The authorities said Mr. Bixby and his son, Steven, ambushed the two officers over a road-widening project outside their home in Abbeville, about 85 miles west of Columbia. Steven Bixby, 40, was sentenced to death. His mother, Rita Bixby, 75, was sentenced to life in prison for not telling the authorities what her husband and son had planned.
