I'm cautiously taking in all this new info about the DNA,.. but if i'm taking verbatim what the article "Investigator: Decomposing Body That Of Caylee Anthony" says...
"Evidence from a Central Florida body farm showed that an odor emitted from Casey Anthony's car's trunk was human decomposition."
"A lead investigator in the case told WESH 2's Bob Kealing that lab results indicated Caylee's dead body was in the trunk of that car. Sources also confirmed that a stain in the trunk was not what clinched the decision that Caylee was in the trunk, but it was the strands of hair that investigators suspected all along were Caylee's."
Transfer?
