Forensics released in the case of slain Florida toddler Caylee Anthony include little evidence linking her death to her mother, court documents indicate.

Caylee's mother, Casey Anthony, has been charged with her daughter's 2008 slaying. But WESH-TV, Orlando, said that court documents detailing forensic evidence in the case released Tuesday shed little light on Anthony's possible guilt, the Orlando, Fla., Sentinel reported.

A large stain found in the trunk of Anthony's car, which investigators reportedly believe was caused by Caylee's body being stored there for days, may or may not have been from a body, an FBI photographic supervisor said in the documents, adding "it is too speculative" to draw conclusions about what the stain might be, WESH reported.

The station also reported the documents as saying that a Maitland, Fla., man saw Caylee and her mother together shortly before her July 2008 disappearance, allegedly telling investigators, "To think I was one of the last people to see Caylee alive, it bothers me constantly."
