18 months after she got to Mason City, she discovered a chilling dark side to the media celebrity she so desired. In autumn of 1994, Huisentruit feared one viewer was taking that sense of intimacy too far. She was convinced a suspicious van was following her.
"She got very, very nervous and was even crying when she called my mom on the phone. So, after that, she was taking even more precautions," Nathe told "20/20."
She was nervous enough to report her fears to the police.
"She thought she was being followed one morning on her way to work. And she made us aware of that right away. And we gave her escorts a few times after that. And no problems. No further problems," said Frank Stearns, of the Mason City Police Department.
Huisentruit even took a self-defense course as her concerns grew.
Since "20/20's" report on Jodi's disappearance five years ago, Minneapolis crime reporter Caroline Lowe got a second job as a police officer.
"One thing I've learned in my training is anniversaries are really important. A 10th anniversary is very important. And somewhere this killer is knowing this. What if the killer's watching? What if his former girlfriend's watching? And I just hope if that's the case, that somebody'll do the right thing and come forward," Lowe said.
Police stress that someone out there somewhere knows something. "The investigation is still very active. We get rumors, tips, theories, things like that, and follow up leads as they come in," said investigator Al Haulbrich.
