OCOEE, Fla. -- What happened to Tracy Ocasio? Five months after she disappeared, detectives still don't have enough evidence to charge their prime suspect with anything.

Tracy’s parents, though, are convinced James Hataway knows something and they opened up to WFTV reporter Kathi Belich to explain why (watch full interview).

Investigators say Hataway was the last known person to see Tracy alive when she gave him a ride home in May. Tracy Ocasio's car was found about 150 yards from James Hataway's house. Her last cell phone ping put her phone practically in Hataway's back yard. That was at 8:30am on the morning she disappeared when her mother called her to see where she was.

RAW INTERVIEW: Ocasio's Parents Talk Exclusively To WFTV

“We just need a break in the case,” said Joe Ocasio, Tracy’s father.

Joe and Liz Ocasio admit they're obsessed with finding their daughter Tracy and finding out what happened, no matter what. Liz says she lies awake at night thinking she'll hear Tracy come in.

The Ocasios spoke with Eyewitness News exclusively about new information on even more inconsistent statements suspect James Hataway gave to police.

Hataway, the man recorded on video leaving The Tap Room in MetroWest with Ocasio in May the night she disappeared, told investigators two different stories implicating his sometime boss who also frequented The Tap Room. Hataway claimed his boss called him, then changed the claim of a call to an actual visit, to tell Hataway not to answer any police questions about his boss and Ocasio.

Police have ruled it all out.

“Everything comes full circle back to Hataway,” Joe Ocasio said.

Just in the last two weeks, a new video surfaced appearing to show Hataway and Ocasio at an Orlando nightclub five years ago, but it turned out not to be them.

Hataway is in jail on unrelated charges, one of them involving a violent attack on a woman. Police say they have investigated all other leads exhaustively and Hataway is still their focus.
