SPRINGFIELD, Mo. (AP) — Police in southwestern Missouri still are searching for a man accused of shooting his ex-girlfriend and one of her sons to death after an argument in the woman’s home.

The Springfield News-Leader  reports that 51-year-old Willie D. Clark is charged with two counts of first-degree murder, three counts of armed criminal action and one count of first-degree assault.
