No Blood Evidence Found in Casey Anthony's Car, Newly Released Documents Show

No blood evidence was found in the car driven by Casey Anthony, the central Florida mom charged with her 2-year-old daughter Caylee's murder, according to documents released Friday.

The new information comes despite investigators' theory that Anthony, 23, stored her little girl's body in the Pontiac Sunfire's trunk before burying her in a wooded lot near the family's Orlando home.

The just-released report, done by Bluestar Forensic, did conclude that human decomposition was detected in Anthony's car — even though no traces of blood were discovered.

Among other documents released Friday by the state attorney's office are images of trash collected as evidence and a T-shirt similar to one worn by Caylee that says "Big Trouble Comes in Small Packages."

Also included is a report on Anthony's cell phone use. Detectives tracked her whereabouts through her cell phone pings around the time her daughter disappeared.

Anthony is currently behind bars but has pleaded not guilty and says a baby sitter kidnapped her toddler. Caylee disappeared in June 2008 but wasn't reported missing until a month later. Her remains were found in December.

Prosecutors say they will seek the death penalty if she is convicted of first-degree murder.

The trial has been postponed from October until January at the earliest — but could be delayed even further.
