Police are one step closer to solving the disappearance of a Michigan woman in the Bahamas after arresting a man in connection with the case.

The man — who was not identified — was taken into custody Wednesday by the Royal Bahamas Police Force after 55-year-old Lynette Hooker vanished from an 8-foot dinghy while traveling to Elbow Cay last weekend, according to a press release.

Police said the 59-year-old man is being grilled by investigators, who are still searching for Lynette, calling the effort a "recovery operation." In addition, the U.S. Coast Guard launched a criminal investigation into the matter.

Lynette's husband, Brian Hooker, reported her missing Saturday night, telling police she fell into the choppy waters during the rough ride from Hope Town to Elbow Cay.

Brian also posted a Facebook message Wednesday morning, saying he was "heartbroken" over his wife falling into the sea. He said he desperately tried to reach her, but the winds and currents drove them further apart. He said he's continuing his search for Lynette, which is his "sole focus.”

But Lynette Hooker’s daughter, Karli Aylesworth, was skeptical about Brian's story, saying she doesn't believe her mother just fell overboard.
