To Dr. David Posey, medical examiner, forensic pathologist, with Glen Oaks Pathology Medical
Group in L.A. Doctor, thank you for being with us. Doctor, Explain to me whether hair can
reveal the presence of chloroform poisoning?
DR. DAVID M. POSEY, MEDICAL EXAMINER, GLEN OAKS PATHOLOGY MEDICAL GROUP: I think if it`s
been used over and over, you can see it in encarnicity (ph). I think.
GRACE: Whoa, whoa. What? What did you just say?
POSEY: Well, encarnicity (ph). It takes time for the chloroform to get into the hair and the
hair has to grow out of the follicle. And so if we`re saying, in this case, for example,
there is just one incidence where the chloroform was used to knock her out, tape her mouth
and so forth, it may not get into hair. So we`ve got to look at the fat, the skin.
GRACE: Let me ask you this doctor. If chloroform got on the hair, if chloroform were put
over the face and got on the hair, would it show up on the hair?
POSEY: I don`t think I know that answer. It could possibly chemically combine with it. But
from my understanding, if it`s used multiple times like as an anesthetic, it can grow -- get
into the hair. And that`s what -- I think the issue here is if it was used more than once,
that may go to what was going on, how many times the intent so far.
GRACE: You know, Dr. Posey, that`s an excellent observation. Many people were deciphering
this to mean did the hair show chloroform use the day Caylee was murdered. But your point is
long-term use of chloroform, repeated usages of chloroform as some type of a sedative or
baby-sitter could actually show up.
Dr. Posey, that, you know, is a whole different look at this. And you believe that extended
use of chloroform would show up in the hair?
POSEY: That`s my understanding. I`ve talked to some toxicologists today. And they said it`s
used for chronicity and not for the acute. Acute would have to have a piece of skin, some
fat, liver tissue, something of that nature. You can extract it. You actually use a totally
different extraction method because chloroform itself is an agent used for extracting most
drugs.
But I think that`s something that I thought about and as I`ve thought about the chloroform
issue over the last few months since it`s been brought up, I`ve often wondered if that isn`t
where the prosecution is going to see if they can show that there`s chronicity of use of the
drug and that.
GRACE: What is chronicity? What is chronicity?
POSEY: Chronicity means being used over and over and over again, as you stated a few moments
ago, the idea of using that as your baby-sitter, you know, knock her out, and don`t have to
worry about her.
GRACE: Got it.

What if Casey just wanted to go out and was desperately looking for them to babysit Caylee.
Maybe out of frustration she "did away" with Caylee.
I have so many conflicting theories about what really happened to Caylee. I bet I'm not the only one.
I can totally imagine that out of her frustration at not having anyone to watch Caylee she
could have given her some medicine to put her asleep, left her sleeping in the car somewhere
and when she returned Caylee was unconscious and unrevivable--
she could have successfully pulled this off before. Maybe she even tried some CPR, etc. to no avail. She made some calls to parents and boyfriend but couldn't reach them. So, she decides to handle things her own way.
