​20-year-old Bob Ryder came to his AA sponsor with a chilling tale

Bob Ryder repeatedly bashed Danita in the head with a clock after he caught her going through his wallet

​20-year-old Bob Ryder came to his AA sponsor with a chilling tale. He told Floyd Nadeau that he'd been partying with a hooker at his home in Lewiston, Maine. Then she began whining with her tales of woe. He also caught Danita Brown going through his wallet.

In a fit of rage, he bashed Danita Brown repeatedly in the head with a wooden clock. Then he dumped her body in the basement of his home.

But here's where the plot thickens. It would take Nadeau almost two weeks to tell the cops of the confession. He claims he was worried about violating Alcoholics Anonymous' teachings on confidentiality -- as if the organization thought it was a really good idea to cover up a murder. 

And when Ryder confessed to police about what he'd done, Nadeau was also implicated. 

According to Ryder, his rendezvous with Danita began in mid-June. He told police and he and Nadeau were cruising for hookers when they picked her up. Ryder paid her $200 and they spent the next few days partying, with Danita occasionally leaving to score dope. 

But when she started to complain about personal and family problems, and Ryder caught her going through his wallet, he smashed her in the head with a wooden clock that sat on a bedside table. 

He then dumped her body in the basement. She was naked from the waist down, and he buried her pants and underwear. 

Ryder, who was discharged from the Marines for mental problems, claims he blacked out during the attack and was experiencing post-traumatic stress syndrome. 

But when he told Nadeau of the murder, instead of going to police, he claims his AA sponsor advised him to buy baking soda to cover up the smell of the body. Nadeau says he never offered that advice. But interestingly enough, he has a long history of violence against women.

Danita disappeared after saying she headed to the pharmacy to fill a prescription

​UPDATE: Danita Brown disappeared after running an errand to the pharmacy.

The 38-year-old woman was engaged to be married to Mike Tibbetts. They'd met in 2005. Their daughters were friends in high school who conspired to set their parents up. 

The couple had gone on to have a son of their own. He's now 4, and he was Brown's ninth child. 

But it seems Brown also had a wild streak. She had a habit of impulsively taking off. When she never returned from a brief trek to the pharmacy, Tibbetts assumed she'd gone to visit friends or relatives. He'd called around, but no one seemed to know where she was. 

It doesn't appear that Tibbetts ever reported her missing. It wasn't until police showed up at his door that he knew his fiancee was dead.
