Liz Ocasio says police recently told her that James Hataway, who's pictured at right, was searching the Internet for ways to commit suicide in the days leading up to his arrest.

"I don't want him killing himself until he tells us where our daughter is, and then I don't care what he does to himself," said Liz.

She calls the fact that he was looking for ways to end his life a red flag.

"If he gets caught for doing something to Tracy, maybe he'll go away for a very long time, and maybe he figured he didn't want to live if he'd be spending the rest of his life in jail," Liz said.

She says police also found evidence that Hataway was interested in neo-Nazism. There was apparently nothing there about Tracy, who's pictured below, nor any indication that he was into cannibalism or vampires as was previously reported. But the 27-year-old woman's mom is still convinced that he knows what happened to her daughter.

"The more that comes out about his background and the kind of person he is and what he's done in the past just makes me even more convinced of that," said Liz. "I think if he didn't do it, he knows who did. I think he knows where she is, and I really do think that he is probably the one that did it."

Hataway is being held in the Seminole County Jail on unrelated charges connected to the attack of Rachel Clarke last year. She accuses Hataway of slamming her head on the ground and trying to strangle her.

Liz says she's pleased that Hataway is behind bars.

"The more time he spends in jail for what he did to Rachel is the more time that we have to find and build a case against him for what he did to my daughter," said Liz.

She says police still consider Hataway to be their only person of interest in Tracy's disappearance. The young woman hasn't been seen since May 27 when she left a MetroWest bar with Hataway.
