I had never heard that theory from the police- do you have a link for it? This wasn’t something they tried to prove in court- and the needle was not introduced as evidence- and I never understood what testosterone would be doing mixed with chloroform anyway? Weird.
Meanwhile- there was a witness at the Walmart in Casselberry (few miles from her house) who had waited on her the week before and said in his deposition he again saw Caylee and Casey on the 16th in the afternoon...don’t know if he testified in the trial however.
Hate to admit but it was from the National Enquirer. Don’t know if it is still there. Sometimes you have to pick the gold out. Of course, they had also reported Casey being pregnant alluding that Jose is he father which, of course, I don’t believe.
One thing I feel certain about the police usually have a lot of experience in these matters.
