It took 25 long years, but detectives now believe they know who is responsible for the disappearance of Tiffany Sessions.
Serial killer Paul Rowles, detectives say, is their main suspect.
With one part of the mystery solved, Tiffany's mother Hillary Sessions hopes for one last tip to bring her daughter home.
"I just want everyone to know it's been a 25-year struggle and it would be nice to put her to rest," Sessions said.
Rowles was already serving life in prison for another murder when he died of natural causes last year.
In his cell, investigators discovered a journal with the date of Tiffany's disappearance.
Tiffany's father Patrick believes it's a strong lead.
"There's the date of Tiffany's disappearance with a number two on it. We know who number one was, it was Linda Frida in Miami," Patrick Sessions said.
In the diary, Rowles also wrote about a large grassy field in Gainesville that investigators believe could have been a dumping site.
The FBI is searching the area now, looking for Tiffany's remains.
But they know someone out there knows something, said Alachua Sheriff Sadie Darnell.
"We want to have this last piece of conclusive connection so the family can finally have some peace," Darnell said.
The University of Florida student disappeared in 1989 while walking along a wooded road near her apartment. Detectives say Rowles lived in Gainesville at the time, and drove a red truck similar to the one Tiffany was last seen in.
Her family knows they will need help connecting all the dots in this case.
"Please come forward, it's very important for me that I find out, because this is my only baby," Hillary Sessions said.
