Investigators are re-examining the final moments surrounding the disappearance of Lynette Hooker, a 55-year-old Michigan woman who went missing in the Bahamas earlier this year. Coast Guard investigators are looking into an account that differs from the one provided by Hooker’s husband. He has said Hooker fell from a dinghy and went overboard, but a source close to the family tells CBS News that Hooker may have returned to the couple’s sailboat before she vanished. The Oregonian reports that authorities are revisiting the circumstances of her disappearance and are considering this possibility as part of the investigation.

The reports indicate investigators are assessing whether Hooker’s movements before her disappearance were different than initially understood. The information cited by CBS News comes from a source familiar with the family, while the broader investigation is being handled by the Coast Guard. Further details on what evidence supports the alternative theory are not provided in the summaries.
