Susan Mears, the Orange County Sheriff's Office crime scene supervisor, was called by the defense and stated that a red Disney bag and a Gatorade bottle were located about 7 inches from Caylee's skull. The state did not cross-examine Mears, reports CBS affiliate WKMG.

The defense followed by calling Dr. Michael Rickenbach, a forensic chemist with the FBI who was declared an expert earlier in the trial, testified about testing various items for chloroform.

Rickenbach tested a steering wheel cover and a car seat from Anthony's car, but did not find chloroform on them.

He also tested the Gatorade bottle and said it contained a liquid, possibly a mixture containing a cleaning product, but low amounts of chloroform were detected in the substance, Rickenbach said, reports the station.

The defense's final witness of the day was Karen Korsberg Lowe, an FBI forensic evidence examiner earlier declared an expert in the trial, the station reports.

She discussed tests performed on items, including clothing and duct tape that were taken from the Anthony family home.

Prosecutors have argued that Caylee was suffocated by her mother with duct tape. The defense contends Caylee drowned in her grandparents' swimming pool. Caylee's skeletal remains were found in December 2008.

Court recessed at noon on Wednesday, because Judge Belvin Perry had a previously scheduled court budget meeting. 

Anthony, 25, is charged with first-degree murder in the death Caylee and has pleaded not guilty. Anthony could get the death penalty if convicted.

The Casey Anthony case was recently reported on by "48 Hours Mystery."
