(CBS/WKMG/AP) ORLANDO, Fla. - The judge in the trial of Casey Anthony ruled that a carpet sample that came from her car trunk, where prosecutors say she placed the body of her dead 2-year-old daughter Caylee, can be used as evidence.

Prosecutors said they believe the stain represents the spot where Caylee's body decomposed. According to investigators, the stain did contain fatty acids that a state expert claims are consistent with body decomposition, reports CBS affiliate WKMG.

The carpet sample also contained high levels of chloroform, according to the expert.

In court filings, the defense called the stain evidence "irrelevant," but failed to produce any factual evidence to support their claim in court Thursday, reports the station.

Therefore, Judge Belvin Perry denied the defense motion to exclude evidence of that stain.

Anthony is charged with first-degree murder in the death of her 2-year-old daughter Caylee. She has pleaded not guilty and has said a babysitter kidnapped Caylee.

The Casey Anthony trial is scheduled to start May 9 with jury selection.
