Missing Lynette Hooker may have returned to sailboat before vanishing in Bahamas

US Coast Guard investigators are looking into the disappearance of 55-year-old Lynette Hooker in the Bahamas. Her husband claims she fell from a dinghy, but a source close to the family told CBS News she may have returned to the couple's sailboat before she vanished — a detail that could complicate the husband's account. The investigation is ongoing.
