ORLANDO, Fla. -- The search for 2-year-old Caylee Anthony reached its 10th day on Saturday. And on Sunday, Orange County officials said they'd involve the FBI if it means asking Casey Anthony specific questions.

The family got some new help Saturday night in the form of a billboard on Interstate 4 near Kirkman Road, where it will be seen by thousands of drivers each day.

Meanwhile, Caylee's mother, Casey, met with attorney Jose Baez for most of the afternoon until just before 6 p.m. at the Orange County Jail.

There are reports that Casey Anthony is going to get to talk to investigators who are not with Orange County Sheriff's Office. Apparently she has told her parents that she doesn't trust the sheriff's office, but would be willing to talk to the FBI.

A representative for Baez said he won't comment on the possibility of the FBI speaking with his client until he hears something official from the Orange County Sheriff's Department.

Meanwhile, Caylee's grandfather, George, continued passing out fliers to anyone who might be able to help. The family estimated that 50,000 fliers had been handed out.

"I need volunteers to help me find my granddaughter," George Anthony said.

Friday was the first time the family had a chance to speak with Casey Anthony face-to-face. George Anthony said it was hard seeing his daughter in jail.

"She's in a particular area and you can only talk to her through a screen and through a telephone, but it was good to talk to her," he said.

George Anthony said whatever can be done to find Caylee is fine by him. He said, if Caylee is anywhere in earshot of a TV, he wanted her to hear his words.

"I love you," he said. "CC misses you. Uncle E misses you, loves you. Remember the moon, the stars, the sky, sweetie. Remember the books. Come home to us."

The Anthony's plan to hold a prayer vigil at their home at 8 p.m. Sunday. Next Friday night, a benefit will be held for Caylee at Speed Park Motorsports in Daytona Beach from 4 p.m. until midnight.

Anyone with information about Caylee should call Crimeline at 1-800-423-TIPS.

Family Faces National Media Attention

The Anthony family faced another day of national media attention on Saturday.

Caylee's grandmother, Cindy Anthony, was on the "Today Show" Saturday morning. She claimed that, during her visit with her daughter in jail on Friday, Casey Anthony told her parents that she can't tell the truth about who has Caylee.

Casey Anthony said she fears that if she does, the girl or others in the family might be harmed.

Cindy Anthony said there have been no threats against her family, but she said she believes there may have been threats against her daughter.

As for whether Casey Anthony provided her parents with any new information about where Caylee might be, Cindy Anthony said her daughter would only hint. She said her daughter doesn't trust the Orange County Sheriff's Office investigators because she feels they've treated her unfairly. But Cindy Anthony said her daughter is willing to talk to the FBI.

On the "Today Show," Cindy Anthony responded to questions about the first 911 call, in which she's heard telling her daughter that she had "already given her a month" to produce Caylee.

Cindy Anthony claimed she was referring to the fact that, during the previous 30 days, Casey Anthony has consistently offered excuses for not putting Caylee on the phone with her grandmother.

Cindy Anthony said earlier Saturday that she got a tip that Caylee was spotted in New Jersey, but she said she now thinks that call was a prank.

When asked about her daughter's bond, Cindy Anthony said, at this point, they don't have the money.

Cindy and George Anthony were also interviewed by People Magazine on Saturday. Caylee's disappearance will be featured in the next issue.
