The founder of a group organizing daily Central Florida searches for missing Caylee Anthony, Tim Miller, said he was furious with Cindy Anthony after what he said was a lack of cooperation.

"I'm pissed off," Equusearch's Miller said. "I feel as though we have been used in this and we are not getting any cooperation. We have done everything Cindy Anthony has asked us to do."

Cindy Anthony apparently heard comments from Miller and bounty hunter Leonard Padilla on CNN's Nancy Grace show and released a statement from a family representative Thursday.

"Leonard Padilla and Tim Miller came to me under false pretenses -- both claiming their sole purpose to find Caylee alive. Tim Miller misrepresented his intentions, and is falsely accusing me of not cooperating with him, when it is evident his motives were to obtain publicity for his organizations at the expense of exploiting my granddaughters' disappearance. Tim Miller tried to discredit Kid Finders Network by falsely stating that they tried to pull out of the search for Caylee. Mr. Miller also claims that he spent twelve hours in my home with my family including Casey, when in fact he spent only a few hours total with me and minutes with Casey. This is an example of Tim Miller following in Leonard Padillas footsteps. Although I feel his organization has a purpose, his misrepresentation has tainted the effort of so many people with good intentions. I would have expected Tim Miller to speak with me one on one, rather than me hearing him on Nancy Grace."

Miller responded to the statement.

"This is about Caylee, period, the end," Miller said. "And I would hope, if something has happened to Caylee, I would hope Cindy would want us out here finding her body too. If Cindy wants us to stop looking for her body, guess what -- we are not going to."

Orange County Sheriff Kevin Beary also sent a message to Cindy on Wednesday.

"Cindy Anthony was on national TV demanding an apology from the sheriff's office," Local 6's Louis Bolden said at the news conference.

"(It) won't happen," Beary said after a chuckle. "It won't happen. We are doing our job. What we need is credible information, especially from her daughter and that is a message I send back to her."

First Appearance Canceled

Meanwhile, a first appearance in court for the mother of a missing Orlando toddler was canceled on Thursday.

Casey Anthony posted bail on new theft charges but remains in jail on a $500,000 bond on charges of child neglect and filing false official statements.

The move comes after a source confirmed to Local 6 that evidence showed traces of chloroform inside Casey Anthony's car.

Detectives are pursuing the chloroform lead in a car belonging to Casey Anthony and information found on the woman's computer, Local 6 reported.

Local 6 confirmed that detectives confiscated Casey Anthony's computer during the investigation and found that someone was on the computer looking up information about chloroform.

Drones Used In Search

A search for Caylee will continue Thursday with high-tech devices. "(Searchers) got drones and potentially another helicopter," Beary said. "Goodness, if you know some of the committees I sit on with the sheriffs, there are a lot of sheriffs who wish they could use drones."

Beary said the group can hopefully provide clues into the case.

"If Equusearch can bring some of that to this area and work it around the airport and find Caylee, that is what it's all about," Beary said. Whether she is alive or passed away, we need to find Caylee."

Casey Anthony, 22, remains jailed on unrelated theft charges after she was charged in mid-July with child neglect and filing a false statement in connection to her missing daughter.

Also, new charges were filed against Casey Anthony. The charges were for theft and check fraud.

Padilla: Shocker Coming

The bounty hunter who helped Casey Anthony bond out of jail last month on the child neglect charge said the world will be shocked by new revelations in the upcoming weeks.

Leonard Padilla and Cindy Anthony appeared on a national talk show Tuesday night.

Cindy Anthony told CNN's Nancy Grace that she believes Caylee is still alive despite evidence indicating the child is dead.

"Right now, my gut is that either she is in Texas, Mexico or Puerto Rico," Anthony said. "I think she is somewhere down there."

"(Cindy Anthony) is living in total denial," Padilla said in response to Cindy Anthony's comment.

Padilla then said in the upcoming weeks, the country will see some revelations in the case.

"When the FBI, who has got some of the finest labs in the world, comes back (with findings), it is going to shock the world over something Lee, Casey and Cindy have known since Wednesday when they released their preliminary findings," Padilla said. "And also, the Dumpster located a mile and quarter away from the boyfriend Tony's home is going to play a big part in this."

Padilla initially said he believed Casey Anthony and that her daughter was alive. He has since changed his belief and has called the mother a liar.
