Fear That Missing Fla. Girl Murdered

Prosecutors in Florida say the case of a missing 2-year-old Orlando girl is beginning to look like a homicide.

A judge set bond at $500,000 Tuesday for the girl's mother, who was charged with obstructing the investigation after investigators say she lied to them.

Circuit Judge Stan Strickland says he's concerned that evidence presented in court possibly implicates 22-year-old Casey Anthony in 2-year-old Caylee's death. An investigator testified that Anthony's car smelled of decomposition when it was found.

Anthony was arrested last week after reporting her daughter missing. The girl hasn't been seen since last month.

Anthony's attorney says there is circumstantial evidence of a possible homicide, but not enough to give prosecutors the confidence to charge Anthony with homicide, kidnapping or any similar offense.

Anthony reported her daughter missing last week, more than a month after the little girl allegedly disappeared.

Anthony was arrested last week after telling authorities her daughter, Caylee Marie Anthony, had been missing since June 9. She was denied bail at a hearing last week. Investigators say Anthony has done nothing but lie to them, but the woman's attorney says she's been cooperating and wants to help investigators.

Anthony's mother, Cindy, said her daughter knows who has the toddler and told CBS News' The Early Show her daughter should be released so she can help detectives.

"I think Casey entrusted her with the same person she's entrusted her with in a long time," she said, "and that person has betrayed her and since then has been threatening her and that's why she can't be 100 percent honest in everything that she's, you know, telling people."

Casey Anthony's lawyer, Jose Baez, said his client wants to cooperate with authorities.

"She is a good mother and has no history of being a bad mother," Baez said. "She wants to find her daughter."

Baez said Anthony doesn't know where the girl is, but he was sending investigators a letter pledging her cooperation. He told The Early Show he expects his client to be released after her bond hearing.

"I expect her to get a bond because of the charges she's facing," Baez said. "She's facing two misdemeanor charges and a very low grade felony."

Sheriff's officials say Anthony has repeatedly lied to them and showed little emotion or concern in interviews just before her arrest.

Orange County Sheriff's deputy Carlos Padilla said Baez hasn't returned detectives' calls to set up a meeting.

"The key lies in the mother, and we would hope the lawyer would allow the detectives to speak to her in his presence to find out exactly where this child is," Padilla said. "This lawyer has taken the time to take this to the media, but he's not yet returned the phone calls to discuss this."

Padilla urged the person who might have the girl but is worried about being prosecuted to drop her off at a hospital or law enforcement office.

Last week, investigators used cadaver-sniffing dogs and dug through Cindy Anthony's backyard looking for the toddler. Detectives say Casey Anthony asked a neighbor to borrow a shovel around the time her daughter went missing.

They said she contacted police last week because the girl's grandmother was concerned.

Anthony told detectives she didn't call authorities immediately because she was conducting her own investigation, according to the charging affidavit. The apartment where she said she dropped off the girl hadn't been occupied in months, and Casey Anthony gave detectives a bogus employer, manager's name and work telephone number, according to the affidavit.
