SLIDESHOW: Person Of Interest

---

Since Jennifer Kesse, 24, disappeared, investigators have continued to believe that a person seen in surveillance photos taken at the Huntington on the Greens apartment complex could offer information in the case.

Last week, Orlando detectives asked the FBI to assist in verifying the person's height and other characteristics from the photos.

Authorities admitted Tuesday that they were not able to determine as much information as they hoped from the photographs.

Investigators are still not sure if the person is a man or woman and did not know the person's weight or shoe size, Local 6 News reported.

Investigators said they are certain that someone other than Kesse was driving her car around the time of her disappearance.

Evidence taken from the car last week was recently sent to labs, Local 6 News reported.

Tuesday, detectives issued a warning to the person who was driving Kesse's car.

"If the person who is responsible for doing this is watching, it is only going to take the smallest piece of evidence," Orlando police Sgt. Richard Ring said. "One little piece of evidence. DNA is not visible to the naked eye and other pieces of evidence are not visible to the naked eye. And, when you walk and you move throughout the planet, you leave traces of yourself everywhere you go."

A $115,000 reward is being offered for information about Kesse's whereabouts.

If you have any information, you are urged to call Crimeline at (800) 423-TIPS.
