Jennifer Kesse was 24 when she went missing in January 2006 after she didn't show up for work. Her car was found at a condo complex about a mile from where she lived.
Click Orlando reports the Orange County Sheriff's Office is following up on a new tip, brought to law enforcement by the Kesse family investigator.
Crews on Friday concentrated efforts on the south side of Lake Fischer, about 12 miles from where she lived.
It's not clear what, if anything, was found in connection with the case.
In the years since her disappearance, law enforcement and Kesse's family have launched several efforts to locate her, including an FBI investigation and multiple searches.
Kesse's family filed a lawsuit in 2018 for access to case records, so they could conduct their own investigation with hired private investigators. The city of Orlando resisted, deeming the case an active criminal investigation.
In March, the family began receiving. The city charged the Kesses $18,648.24 for access to files, which the family paid using donations to a fund used to finance search efforts.
The tip that led to last week's lake search stemmed from that fight for records.
Drew Kesse, Jennifer's father, said the tip came from someone who saw the family's battle to get unredacted police records on the case.
"This (search) was seven months in the making," Drew Kesse said, adding that he will continue to follow up on credible tips.
"We'll see how this works out and move from there. We keep going, we keep investigating," he said. "We ask the public please stick with us, please believe in us. Believe in Jennifer and if you know something and have called something in before that you think has not been worked, give us a call."
People with information are asked to call the Kesse family tip line at 941-201-4009.
