BOKEELIA, Fla. - We are hearing exclusively from the mother of Daniel Proctor. He's the longtime suspect in the disappearance of Amy Patterson. The teacher from Bokeelia has been missing since last July.

After a year of searching for Patterson, deputies were led to Howard Road and Bahama Way because Proctor, Patterson's ex-husband, said they'd find a body there. He finally spoke up after being sentenced to life in prison on a theft case in Alabama. Whether or not the remains they've found are those of Patterson's has yet to be seen.

"It's her," Proctor's mother Joyce Rosenbaum said. "I know it's her. Because when you get a computer in front of somebody with a map on it to where he lived, and he puts his finger and says that's where it is, and that's exactly where they found her."

Rosenbaum says her son never said anything to her about what happened to Patterson until Tuesday.

"He told me yesterday that he don't remember anything because they had been out drinking, they came home, they ate, and she told him she was going to bed because she didn't feel good, she was tired," Rosenbaum said.

That's when Daniel Proctor told his mother about the day in 2011. He went outside to play horseshoes, took a nap, and when he woke up, he said he found her in the bedroom.

"He said she was dead, had marks on her throat," Rosenbaum said. "I said, Danny, when you went in there and found her, how long did you keep her in the house? He said, mama, just a couple hours."

Rosenbaum had feared this was the case all along.  Now, she worries, behind bars, her son could harm himself. She's asked detectives to watch him closely.

"He did look at me yesterday and said mom, I'm sorry," Joyce Rosenbaum said.

Proctor's mother says her son has already admitted he took Amy Patterson's life. But, at this point, it's not been confirmed that the body found is in fact, hers. The autopsy will determine whose body it is, and how they died.
