A potential break in the case of a Florida woman who has been missing for three years and whose photo later turned up on dating sites may have come from a convicted killer.

David Russ, who confessed to a 2007 murder, claims to have information about the disappearance of 24-year-old Jennifer Kesse and had his lawyer contact her father, MyFOXOrlando.com reported.

Russ is in the Seminole County Jail awaiting sentencing after pleading guilty to killing Madeline Leinen. He asked to meet with Kesse's father, Drew Kesse.

"I think it's just one more lead that has to be followed up on," Kesse told MyFOXOrlando.com. "If it turns out, then we have something to go on."

Kesse wouldn't disclose anything about what Russ told him.

"I am not going to talk about the information that was relayed,” Kesse said. “It's just not pertinent at this point."

Detectives say they're investigating Russ' claims. They don't believe he has information that could break the case.

Jennifer Kesse was last heard from the night of Jan. 23, 2006, and never showed up at work the next morning at Westgates Resorts, where she managed the timeshares financial department.

Her car was found abandoned about a mile from her home. Surveillance video taken on the grounds of her Orlando apartment complex shows someone parking the black Chevrolet Malibu on the afternoon of Jan. 24.

There have been few other leads.

About a year-and-a-half after her disappearance, her photo appeared with people's profiles on dating Web sites for senior citizens and lesbians. Police said the postings had nothing to do with the case.

Anyone with any information is encouraged to call the Orlando Police Department at (407) 246-2470 or the Kesse family tip line at (407) 722-2162.
