A man has been arrested through DNA and genetic genealogy in the 1973 killing of 11-year-old Linda Ann O’Keefe. O’Keefe was last seen alive on July 6, 1973, as she walked home from summer school. Her body was found the next day. O’Keefe’s suspected killer, James Neal, was arrested this week. Neal left California after the killing and went to Florida where he changed his name.
