2011.06.21 TRIAL Day Twenty-four (Afternoon Session)

[mendz]

baez has been harping on this qualitative/quantitative argument since chloroform came up with dr. vass. he seems to think not doing the quantitative test was a huge mistake. i think baez just doesn't get it, as usual...

 

[ahoyhoy]

I am SO HAPPY right now!!! HAHAHAHAHAHA!!! Never ask a question you don't know the answer to......

 

[webhound]

Thank you! Only JB could slip up and get this info about his client to the jury.

And now that the jury knows she was out of jail at that time, who is to say that it wasn't the accused that "moved the body"?!

 

[Tulessa]

When this is over no only will I not watch IS or HLN, I hope to never get involved in another case again.
The more I learn about our "justice" system, the more I fear there is none.

You have to cover one in October with me. I depend on you guys being there. If not in person, then here, for support.

 

[Steely Dan]

This guy is not helping JB that much IMO.

 

[monique]

No freakin wonder JA didn't object to his testimony!!!

 

[gitana1]

This guy is hurting JB's case, IMO. he said not to bother doing a quantitative test because it is a volatile liquid and would likely evaporate quickly. And yet, even after a lot of time for it to evaporate, Dr. Vass found a high level.

 

[pinkfly]

JA or Linda must be trying real hard right now to not giggle.

 

[matou]

Gas bags don't hold onto their samples well after 2-3 days.

 

[AnotherGladysKravitz]

How much are alterations?

 

[RedSox Mom]

BOOM.......whole carpet would have had greater (2xs or more?) amount of chloraform than just the small piece. OMG... JB is burying KC all by himself!!!!!

 

[Reality Orlando]

i just learned more about chemistry, ie info regarding volatility, chloroform, and quantitative vs. qualitative from this research scientist.... than I have in my lifetime.

I think he's helping negate the point that JB is trying to make...

anyone?

This guy should be a teacher. Wow, he's great at explaining complex situations.

Marcus Bain Wise- analytical chemistry Phd...additional train @ Oakridge almost 27 years started right out of school...belongs to organizations - Boy Scouts of America - no professional organizations now....published how many times don't know the number probably 15 - 20 lectured on topic of analytical chemistry and given presentations and won awards in that area - some in the past...first time ever testified in court....

need to Enter Dr. Wise as expert in analytical chemistry - expert research scientist

works on challenging scientific problems need to be addressed solved to push frontiers to next level...forensic scientist ccan be reserach scientist...often does research in forensics...use science in courtroom....Oakridge Nat Research lab...challenging ...we develop forensics....we do not use protocols as in a Forensic lab...evidence type samples are not as common in type of work we do...forensic lab - another difference in labs are protocols usually in place in forensic lab that is not in a research lab (object- sustained estab.foundation)

different types of labs and somewhat familiar with their practices --somewhat...forensic lab much more rigid standards than research lab (object- foundation overruled if witness can answer) have not worked personally in a forensics lab...you are aware they are much more rigid standards to hold up in court...protocols are much more rigid -haven not run protocols don't know their standards...in Research & Development - analytical needs that arrise - protocols written steps what must be done in each and every case...methods not written routinely like driving a car....do it day in and day after day after day - no proficiency exams for forensic samples - as well as quality control...in these cases we are not running a routine procedure ....part of the reason ....any protocols in place in your lab to prevent contaminationl...we run light standards...for (object- lead 0verrule) you have an item going to test - no protocols prevent contamination of the item....do you have any quality control practices and procedures in place prior to it reaching the machine....don't understand how it could be contaminated....

are you aware of contamination? no...(object -sustain) as your research is to expand boundaries of science - primary focus....analytical chemist not aware of major sources of contamination...where you witness in testing items....anything place in your lab to monitor for contamination...no background machine runn

run a sample of GCMS - dr. Arpad Vass asked me to run it...they were in his office...he was not in there that day....left open? key left....don't remember where they were in his office...dont recall....container in? shipping containers don't remember but one was a bag and the other a metal can....ran a test using instrument...GCMS...qualitative analysis tells what are in the sample ...quantitative tells how much there....advise Vass a quantative analysis not mean anything in this stain? object - vague - sustained

items askec to test in this case did you advise Dr. Vass quantitiative analysis would not mean anything in this case....at that time we didn't talk bout quantiatavie......missed some


several peaks there relative height of those peaks is approximate of relative amounts there...just compares one chemical to another ...not a quantitiative analysis....we performed a second test before decision reached not do a quantitative was his advise yes....ever done a quantitative analysis to determine how much chloroform - not quantitfied because a meaningless number.....trunk is free flowing enviornement....chlroform is volitle chemical evaps quickly...like gasoline...little drop on finger -see it and strong smell...after 20 min can't smell anymore - liquid vaporize moved from fingers to atmosphere swept away...chlroform is that type compound a drop on a surface evaps over period/hours/days it will decrease ...rate decrease depends on temperature...chemical nature of surface...surface exposed to blowing air....all effect concentration decrease...slow down the volitilty down? no not the volitilty but prevent air escape from trunk...qualitative analysis on small piece of carpet...get a number of x number of micrograms the amount on that carpet at a particular snapshot in time...doesn't represent whole carpet...quantitative measure on that little piece on carpet....could be little less or whole lot less when original could have been 100 to 1000 x's greater...we really want to know amount first there...because you don't have the history didnt bother checking (object) did not know history and temp of the trunk over period of time varies every single day....however many days it has been going down...one day vs. 30 days...one day would be considerable higher....no amount of chloroform - because if I did it would been set in stone what that number was and it is not meaningful cannot be related to amount original there....a gas bag sample.....tested that virtually nothjing there - experience with gas sample bag not surprising not show presence of chloroform...don't know what was in air....don't know the vapor but we measured the piece of carpet in the trunk

 

[Azcrabcakes]

LOL. JB asked him if this is the first time he's testified. I'd love it if he asked JB 'is this the first time you played a lawyer on tv?'

I really needed some comic relief! THANK YOU!

 

[reeseeva]

Do you think Baez ascribes to ICA"s words of "With Great Power, Comes Great Consequences"

 

[allycat1208]

I have not seen it all today, but was there any good laughs from the witnesses, like our good ol' Dr. Spitz?

 

[everyoneneedsavoice]

Did I hear LDB say today, "that when they cross examine Ms Casey", she was talking about this new possible witness from the jail. Just wondering if she will be on the stand for sure. tia

Why, yes...you sure did!

I had to rewind several times to make sure I heard that right!

 

[Florida Native]

No and I think it was a warning shot across the bow of Baez really. Showing him exactly what they will use to impeach her. They are still investigating this person. But I truly believe they put Baez on notice he made a big mistake.

Which with JB's track record, I expect to see her on the stand ASAP. :crazy: He seems to do the opposite of what a rational attorney would do.

 

[technicalconfusion]

He's making the chloroform sound so much worse. What the hell is JB doing?

Trying to prove Caylee wasn't killed by duct tape???

 

[cluciano63]

OT, this guy has such a jolly look about him...
