The jailed mother of a missing Orlando toddler has continued to communicate by phone with her family despite the release of tapes of their conversations by authorities, but their recent conversations have stuck to everyday topics.

Casey Anthony, 22, is guarded in jailhouse conversations Wednesday and Thursday with her brother Lee Anthony, who is, in turn, veiled in his responses. Orange County sheriffs have made a number of Casey Anthony's exchanges from prison public during the ongoing search for her 2-year-old daughter Caylee Marie Anthony.

Much of the recent conversations involve small talk, with Casey Anthony asking how her family is doing. In the Wednesday conversation, her brother also asked if "anything has changed" and "whom I can trust and all those things."

It isn't clear what he was referring to. A transcript of the phone call produced by MyFOXOrlando.com quoted Casey Anthony as responding, "I don't really know. I'm not level."

A closer listen to the actual tape, however, suggests she actually said, "I don't really know on that level."

On Wednesday, a judge denied a petition to lower Casey's $500,000 bond. Her attorney, Jose Baez, will file another appeal to the state Supreme Court, according to MyFOXOrlando.com.

Anthony is a person of interest in her daughter's disappearance but has been charged only with child neglect, false statements to police and obstructing an investigation.

When Anthony and her family first reported Caylee missing on July 15, she told police the girl already had been gone for a month. She also claimed that Caylee had been taken by a baby sitter, who also vanished.

Since that time, police have expressed doubt in many of the details of Anthony’s story. They also have testified that they found hair samples and detected an odor of human decomposition in the trunk of a car Anthony had been driving.

The case has grabbed national headlines, making the cover of the latest issue of People magazine, which hit newsstands on Thursday.
