Casey Anthony's trial (Day 28) halted on Saturday because of unexplained legal issue, according to an announcement of Judge Belvin Perry.

At 9:00 am, when the trial started, the judge and the lawyers went into a side room to talk in private. After 40 minutes later, Perry emerged and announced that the trial will be halted until next Monday 8:30 am.

About the details of legal issue, neither defense lawyer Cheney Mason nor prosecutor Jeff Ashton gave any comment. I can't tell ya, Ashton told the press.

Before the announcement, the prosecution and defense lawyers discussed if the expert witness Dr. Kenneth Furton would be allowed to testify about opinions, even though he didn't open for prosecutors in advance.

The trial will resume Monday at 8:30 a.m.

About Casey Anthony Trial

Two-year old Caylee was last seen alive on June 16 and it was only on July 15 that she was reported missing by her mother Casey Anthony to the police. Cindy, Casey's mother had also alerted the police by calling a 911 dispatcher and saying that she had smelled a dead body in the trunk of Casey's car that was spotted in an impound lot. The car was later towed by authorities for forensic analysis.

Initially, Casey told the police that a babysitter called Zenaida Fernandez-Gonzalez (Zanny the nanny) had abducted Caylee. Investigations showed Casey was lying as the babysitter Zanny was fictitious. Five months later, in December 2008, Caylee's decomposed skeletal remains were found in a wooded area near the Anthony home by a meter reader who was relieving himself.
The prosecutors say Casey chloroformed Caylee and then put duct tape over her nose and mouth, suffocating the girl.

Casey's lawyers claim Caylee was not murdered. They say the toddler accidentally drowned in the family swimming pool and George, Casey's father, helped her keep the death a secret. George has denied the claim.

Casey has been charged with seven counts, including first degree murder, aggravated child abuse and misleading the police in the death of Caylee. If she is convicted of first degree, she could be sentenced to death by the seven-woman, five-man jury. The trial is expected to take another 2-3 weeks before a verdict is reached.
