ORLANDO, Fla. -- Channel 9 has learned some of the clues investigators might have uncovered from Jennifer Kesse's car. The 24-year-old disappeared almost a month ago.

"Something happened there and that's my daughter, a living being, and she was taken from that car," Jennifer's father, Drew Kesse, said.

He said, even with the splashes of processing fluid used to check for evidence, his daughter Jennifer's car is cleaner than she ever kept it. Detectives likely have most of the items of clutter that used to be there, hoping for clues.

"I'm sure they took everything they possibly could out of it and I hope they pulled something off of something in that car to give them a direction," Drew Kesse said.

Fingerprint dust lines the steering wheel, gear shift, door handles and anything else a suspect might have touched. The seats and floors were likely vacuumed to collect hairs and fibers. Soil tests could show where the mud caked on the bottom of the car came from.

"It's just logical thinking of the technology they have nowadays that they have to have something within the car," Drew Kesse said.

Investigators do know, from Jennifer's credit card bill, that she filled her gas tank in Ft. Lauderdale before driving back to Orlando. She went to work, then home and should have had about half a tank left. That's about what's there now, so her attacker may not have taken the car very far.

"It seems to be right to us, but again we're not the professionals, we're letting them do their job and we're doing what we need to do on our end," Drew Kesse said.

Detectives said any evidence from the car has already been sent to a lab for testing. The Florida Department of Law Enforcement handles fingerprints and DNA. The FBI does trace evidence.

Channel 9 has learned there have been requests to expedite any results in this case.

The Kesse's did have a bit of a let down Friday. They were hoping specific information about the person of interest seen walking near where the car was found would be released Friday. The FBI is still calculating the person's height and show size. Those results won't be ready until Tuesday at the earliest.
