ORLANDO, Fla. -- Threats of violence against the mother of a missing Orlando girl and her family have escalated after DNA results indicated the child is likely dead and a decomposing body was in the woman's trunk.

"(Callers are saying) kill the (expletive), burn the (expletive) and fry the (expletive)," the bounty hunter who helped free Casey Anthony, Leonard Padilla, said.

The threats have become so frequent and so violent that Padilla said Casey Anthony and her family are no longer safe and are easy targets for people who could harm them.

"Most of (the callers) are nuts," Padilla said. "They are abusive and they are probably out of their minds but you can't pass up the fact that somebody might just do something stupid. Something has to be done and the safety issue is paramount to us."

A group of people were waiting outside Anthony's parents' home for a chance to confront the family about missing Caylee Anthony.

"(Casey Anthony) does not deserve the air she breathes," resident Denise Payton yelled outside the Anthony home. "And her parents, I don't know how they live with themselves."

"They are disgusting people," resident Tamara Silva said. "Anybody with any kind of sense whatsoever knows they are hiding whatever and they know," Silva said. "I knew from day 1 that baby was not alive."

Padilla said he is throwing Anthony back in jail and revoking her bond for her safety and his piece of mind.

Padilla said he wants to get Anthony back behind bars now that there is talk that protestors may be planning a demonstration against her.

Drone May Be Used In Search

Searchers claiming to have better location technology than most police departments, including drone planes and sonar, will launch a massive search for missing Caylee Anthony over the weekend.

Caylee has been missing since mid-June and her mother, Casey, was arrested on charges of child neglect and filing a false statement in mid-July, about 31 days after she said she had last seen Caylee.

The group of volunteers from Texas is in Orlando planning the high-tech search for the child.

One of the people scheduled to be involved in the Equusearch effort will be the mother of missing student Natalie Holloway. Holloway vanished in Aruba in 2005.

Equusearch founder, Tim Miller, said his group has helped with a lot of major missing person's cases, including the Elizabeth Smart case.

Miller said he hopes to find Caylee alive.

"My own daughter disappeared when she was 16 years old," Miller said. "The police said she was a runaway and I knew she wasn't. And 17 months later her body was found two miles from my house."

Besides Sonar and drone airplanes, the group also could use ground-penetrating radar in the search.

The effort begins Saturday.

Results Show Caylee Likely Dead

The search will be launched despite new FBI DNA results that lead police to believe Caylee is likely dead.

Hair samples found in the trunk of Casey Anthony's car are likely that of her daughter, Caylee, a sheriff's office source told Local 6 News.

The hair samples do show signs of decomposition, Local 6 confirmed Thursday.

However, there can be false positive results with the testing, Local 6's Jessica D'Onofrio reported.

Also, preliminary air samples taken from the vehicle indicate the foul odor in the car was that of a dead body.
