The trial of Casey Anthony resumed on Tuesday (Day 24) with the prosecutors doubting the defense lawyer's claim that Casey's 2-year-old daughter Caylee died by drowning in the family swimming pool.

According to the prosecutors, a female prisoner, who was incarcerated in the same prison as Casey, had a kid who drowned in the pool in 2007 - a scenario similar to what the defense lawyer said in the opening statement.

Prosecutor Linda Drane Burdick said they got the new information from an anonymous phone call made at the end of last week. They are investigating the information given.

However, the woman in Casey's neighboring prison cell said she never spoke to Casey. And, no one is certain whether she is still in jail or has been already released.

On Tuesday, two expert witnesses testified.

Jane Bock , a forensic botanist testified that Caylee's corpse might have been in the wooded area, where it was found, for about 2 weeks, according to the leaf litter at that time.

In a photo that showed Caylee's remains, leaf litter and dirt covered the eye sockets and only the top of the skull is visible.

When prosecutor Jeff Ashton said a hip bone had been found nearby under four inches of leaf litter, Bock replied, it could have been buried by a dog.

When Ashton sniffed at that possibility, the witness said that's what dogs do.

Another expert witness, Dr. Richard Eichlenbloom, also testified that he didn't find DNA on the duct tape that covered Caylee's face.

Ashton tried to debunk Eichlenbloom's authority as a DNA scentist, his methods and his intentions?although Ashton fought to admit DNA science himself as evidence in 1988 and 1989.

Meanwhile, Eikelenboom cannot give testimony regarding the decomposition fluid found in Casey's trunk until next week because a full report of his opinions was not submitted in time, despite continued warnings.

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.
