Press Conference on Missing 2 Year-old Caylee Anthony

Carlos Padilla holds a press conference on the whereabouts of 2 year-old Caylee Anthony. Casey Anthony, Caylee's mother, was arrested on child neglect charges in connection with her daughter's disappearance and is being held at the Orange County Jail. Deputy Carlos Padilla said they are still actively searching for Caylee and treating this as a missing person’s case. But their frustration grows with each day.

"We still feel the key lies with Casey," said Padilla. "And if she would just open up and tell us where Caylee is, this could end quickly."

In other developments Thursday, Casey asked that the only visitors she be allowed are her mother, father and brother.

Casey Anthony is being held in jail on $500,000 bail. She's been charged with child neglect, making false statements and obstructing an investigation. Police say the 22-year-old mom lied and didn't report her daughter Caylee missing for more than a month.

Casey Anthony hasn't been charged with her daughter's disappearance; she told detectives that she left the toddler with a babysitter named Zenaida.
