Casey Anthony's cell phone records from June 16 -- the day investigators believe something may have happened to her daughter Caylee -- show she made nearly a dozen calls in less than five hours, records obtained by Fox News Channel showed.

Anthony called her mother seven times, her dad once, her boyfriend and two other friends, the records showed.

The woman's cell records from June 17 were not available but on June 18, the records showed Casey Anthony tried calling her mom and dad six times in less than an hour.

Attorney Questions Timeline

Meanwhile, Casey Anthony's attorney, Jose Baez, said he finds it odd that investigators are zeroing in on three dates in June.

Video shot on June 15 shows Caylee Anthony reading a book at a table.

However, deputies are pointing to June 16 as the day something happened to Caylee, Local 6's Erik von Ancken said.

Detectives said on June 17, Casey Anthony borrowed a shovel from a neighbor and on June 18 the woman was spotted backing up her car to her family's garage.

"I have not heard that theory," Cindy Anthony said. "Out of their mouths today, to me, all of them (said) they're looking for a missing child. That's what I'm doing. I'm looking for a missing child. And that is what I'm asking the public to do."

Publicly, the Orange County Sheriff's Office said 100 percent of their resources are going into finding Caylee Anthony.

Privately, detectives admitted that Casey Anthony is just as much a focus of their investigation, Local 6 reported.

Casey Anthony remains jailed on $500,00 bond as a national search continues for her daughter.

Cadaver Dogs Records Requested

During the initial investigation into Caylee Anthony's investigation, two different cadaver dogs hit on the same spot in the child's grandparents back yard.

Deputies said the dogs were trained to locate gases given off by a decomposing human.

However, the missing child's grandmother said the dogs could have been confused by their handlers.

"I went online this morning and read up on a lot of cadaver dogs," Cindy Anthony said on in July. "Cadaver dogs could be cued by their owner."

Local 6 has learned that Baez has filed a motion asking for all background information on the dogs, including their training records.

Family Conducts Own Search

Cindy Anthony said that her family is conducting its own search for Caylee.

"I was out yesterday doing my own foot-pounding up in another county based on some tips and some leads, so yeah, we're all out there kind of doing our own thing," said Cindy Anthony, the grandmother of Caylee Anthony.

Casey Anthony said she left Caylee with a baby sitter named Zeniada Gonzalez at the Sawgrass Apartments in Orange County.

"I believe my daughter. I know that someone has my granddaughter," said George Anthony, Casey Anthony's father, who suggested on Tuesday that that the kidnappers may be under surveillance.

Orange County sheriff's officials cautioned anyone against conducting their own investigation.

"Obviously we don't want anybody who's not trained in law enforcement and proper procedures to do anything out of the norm that they think they should be doing," Orange County sheriff's Capt. Angelo Nieves said.

But Cindy Anthony said she has recruited a team to help her in the search.

"We get tips every day on Zenaida Gonzalez. They have over a thousand Zenaida Gonzalezes that are linked to the places that Casey told them to look, so it does take time to search through. Private individuals (are) doing it, authorities are doing it, private investigators are doing it, family members are doing it," Cindy Anthony said. "One of those tips is going to say, 'Hey, I know exactly where (Caylee) is at,' and it's probably going to be a very covert operation."

FBI Checks Threats

Meanwhile, FBI agents are now checking into some of the daily threats targeting the family of Caylee Anthony.

"The sheriff's department (and) the FBI are looking into this," George Anthony said. "Whenever you start threatening people with bodily harm, that's a problem."

The Anthony family said they have received threats every day by letter, e-mail or phone.

A search continues for missing Caylee Anthony.
