JACKSON, Miss.—A man who was executed in Mississippi last month for killing his estranged wife admitted to another killing, and his confession could resolve a 2007 cold case, a prosecutor said Monday.
Before his execution on Nov. 17, David Neal Cox told his attorneys he killed his sister-in-law Felicia Cox in 2007 and provided detailed instructions on where investigators could find her remains, said John Weddle, who is the district attorney for several northern Mississippi counties.
