More info released in Anthony case

Images of a syringe, a Gatorade bottle, a car seat, the contents of a car's trunk and a kit used for testing chemicals are among the photos released by prosecutors in the murder case of Casey Anthony, who is charged with killing her daughter, Caylee.

Prosecutors trying the first-degree murder case of Casey Anthony released the photos, which could be used as evidence, on Tuesday.

The FBI tested dozens of items, but found very little scientific evidence linking Casey Anthony to Caylee's death, Local 6 reporter Mike DeForest said.

An FBI agent thought a stain in the back of Casey Anthony's car resembled the outline of a child's body, but lab tests were unable to determine what the stain was or what caused it. Another stain on Caylee's favorite doll was also determined to be insignificant.

The day Casey Anthony's mother, Cindy Anthony, discovered the foul smell in her daughter's car, she also found a knife inside, which she later admitted to washing. The FBI found residue on the knife, but could not match it to the duct tape later found around Caylee's skull.

Other than similar looking garbage bags, duct tape and a laundry bag, the FBI was unable to create many links between the crime scene and the Anthony family's home or Casey Anthony's car.

The FBI has not found a single hair, fingerprint or DNA sample that scientifically proves Casey Anthony was in the woods where Caylee's body was found.

Casey Anthony, 23, has pleaded not guilty and claims a baby sitter kidnapped Caylee, who was 2 years old when she was reported missing in 2008.

Forensic testing revealed traces of chloroform in Casey Anthony's car. The chemical compound is used to induce unconsciousness and is also a component of human decomposition.

Televised video featuring an interview with Casey Anthony's brother, Lee Anthony, was also released. A missing persons flier seen in the video shows a piece of duct tape holding the flier to a pole.

Caylee was last seen alive in early June 2008, but she wasn't reported missing to authorities until a month later.

Meanwhile, the media liaison for the Casey Anthony defense team has resigned.

According to a news release, Marti Mackenzie will no longer be working with the defense team, and all media inquiries about the Casey Anthony case will now be directed to Liz Brown, at DePaul University College of Law Legal Clinic.
