<<<(WESH) ORLANDO, Fla. -- New evidence released on Friday in the case against Casey Anthony may finally include the smoking gun prosecutors have been seeking since her arrest.

According to forensic reports, the presence of microscopic flies in Anthony's trunk is important because the flies feed on decomposition. Reports indicated the insects were also found at the site where Caylee Anthony's body was found in December.

The forensic report was dated Sept. 22, 2009. Inside the trunk and a trash bag from Anthony's car, investigators recovered a large number of so-called coffin flies, which are gnats that feed on human decomposition.

Forensic botanist Neal Haskell concluded that a large number of the insects found on paper towels inside a trash bag meant there was decompositional fluid on the towels.

"Given the association of the towels with the car, it seems most likely that the paper toweling was used in an attempt to clean the decompositional fluids purged from the remains in the trunk of the car," the report stated.

In addition Haskell said the insects found in Caylee's skeletalized remains and near the body indicated insects started colonizing there in late June or early July 2008.
