ORLANDO, Fla. — Orange County Sheriff's investigators ended a 3-day search of a lake in Gotha Friday after an investigator hired by the Jennifer Kesse family provided a tip.

The Sheriff's Office confirmed the search was taking place Friday afternoon at Fischer Lake. It's on the east side of State Road 408 and is just north of Lake Nally.

That search ended Friday evening with no new findings. Kesse's father, Drew, said the dive team concluded their search around 5:45 p.m. "with negative results."

Kesse went missing in January 2006. Police think she was abducted while leaving her Orlando condo. Her car was found days later at an apartment about a mile away from home.

Her parents, Drew and Joyce Kesse, took over the investigation in October after settling a lawsuit with Orlando Police to get access to 14,000 pages of electronic files and dozens of hours of video. They hired a legal team and some investigators of their own to go through the evidence.

Kesse says their team has plenty of other leads, but they are still asking for help.

“The public has been incredible to Jennifer, but we still need your help," he said. "She’s not home yet, we haven’t touched the right person, and we haven’t got the right lead."

"We'll keep on working for Jennifer until we find her, and we will never give up and she knows that," he added.
