Investigators first believed Doris Worrell was killed in a botched robbery after her husband found her fatally shot at the South Georgia business they ran in 2006. When suspicion later turned toward Worrell's husband, he fled the U.S. to live in Costa Rica with the couple's live-in nanny. Nearly 19 years later, Jon Worrell was jailed on murder charges Thursday in rural Coffee County, where the sheriff said authorities never gave up on the cold case.
