ORLANDO, Fla. -- The Orlando Police Department expanded its search for Jennifer Kesse on Thursday, but found no leads in the case. Channel 9 has learned private search teams have shown up to help look for the missing 24-year-old last seen 10 days ago.

The first private search and rescue team is from Melbourne and, when they heard about the massive effort being organized to find Jennifer, they wanted to help right away and showed up Thursday afternoon.

"You always gotta have hope. Elizabeth Smart case, she was 100 yards from her house,” said Fred Golba, search and rescue team.

Golba, a retired firefighter, started in the woods that border Jennifer's condo. But his cadaver dog, Astro, didn't find anything and they moved to the next location.

"There's not enough time in the day and I don't think it's calculable the scenarios may happen. If you do a grid elimination, you will cover every possible scenario,” he said.

Orlando police have been grid searching different wooded areas for days, starting near Jennifer's Mosaic at Millenia condo and the apartment complex where her car was found a week ago.

On Thursday, 20 officers, five yards apart, scoured thick brush searching for anything suspicious. They found the gate wide open at a retention pond. It's within walking distance of the condo, but so far they've found nothing.

"It's perplexing, definitely, that it is. But all these officers here have been trained. They all have families. Their hearts are still in this,” said Lt. John O'Grady, Orlando Police Department.

It's those hearts and the support from strangers like Fred Golba that are keeping Jennifer’s parents strong.

"She feels the love and support of her family and friends and community and that’s gonna help her endure until we find her, and we're gonna find her,” said Jennifer’s mother, Joyce.

Orlando police have now given the go ahead for search and rescue teams to help look for Jennifer. They are not restricted as to where they can go. Most are trained that if they find something that could be evidence, to leave it alone and call law enforcement.

People started signing up Thursday to help in the search for Jennifer this weekend. A special office has been set up at the Mall at Millenia. The search was put together by a local group called Child Watch.
