The family of a Michigan woman who recently disappeared at sea in the Bahamas fears that her husband will not be charged until authorities find more evidence.

Lynette Hooker and her husband of 25 years, Brian Hooker, had been living out on their sailboat in the Caribbean when she vanished over Easter weekend.

Brian Hooker, 59, was arrested by the Royal Bahamas Police Force on Wednesday. Under Bahamian law, the authorities have four days to decide whether or not to charge him before they must release him.

Karli Aylesworth, Lynette Hooker's 28-year-old daughter, told The Detroit News that she was told on Thursday that police were questioning her stepfather. 

Steve Hansen, Aylesworth's boyfriend, told the outlet that the family does not expect Brian Hooker to be charged 'unless they find blood on the dinghy or her body or some key evidence like that'.

'They just want to put pressure on [him] until they have something,' Hansen added.

In a statement through his attorney on Friday, Brian Hooker claimed that the rough water conditions caused his 55-year-old wife to fall overboard on April 4.

The pair were out at sea on the roughly eight-foot-long vessel while their main boat, Soulmate, was docked near Elbow Cay.

Brian Hooker said his wife had the keys to the dinghy, which caused the engine to automatically shut down when she fell overboard.

In text messages he sent to a friend, he said that Lynette Hooker tried to swim back to the boat but that the wind separated them 'pretty quickly', CBS reported. 

According to him, he had to paddle for hours until he reached Marsh Harbour Boat Yard at around 4am on Sunday. He alerted someone, who then called police about Lynette Hooker's disappearance.

Aylesworth has felt that her mother's disappearance has been suspicious since the beginning. 

She has pointed out that Lynette Hooker is an experienced sailor and that it wouldn't have been like her to clumsily fall out of a boat, even in choppy waters. 

She also found it hard to believe that her mother had the keys since her husband is 'always' the one driving.

In an interview with CNN, she questioned why Brian Hooker did not try harder to find her.

'Why wouldn’t he drop anchor and look for her?' she asked. 'Why did he paddle the other way? If my significant other fell into the water, I’d be freaking out and going after him.'

There is also a history of domestic violence between the couple. In February 2015, Lynette Hooker was arrested in Kentwood, Michigan, on charges of assault and battery/simple assault.

She was released because there was not enough evidence to determine who started the fight. Both of them were described as 'intoxicated'.

At the time, Brian Hooker said she 'struck him in the face multiple times', according to the police report. He was under the impression his wife was 'fooling around' with another man.

Lynette Hooker claimed that her husband had hit her in the forehead and choked her. According to the police report, she had no visible injuries, while he had a swollen and bloody nose.

Aylesworth has said her mother and stepfather have 'a history of not getting along, especially when they drink'.

And in an interview with Fox News, she said there's also 'history of him choking her out and threatening to throw her overboard'.

Brian Hooker denied Aylesworth's accusations in a statement to the Daily Beast. He has strongly denied that he had any involvement in his wife's disappearance.

His lawyer, Terrel A. Butler, added that he 'has been cooperating with the relevant authorities as part of an ongoing investigation'.

The US Coast Guard has opened its own criminal investigation and NBC learned on Thursday that the Royal Bahamas Police Force has requested American assistance.
