You're listening to continuing coverage from the trial of Corey Richards, from the Hidden Killers podcast and True Crime Today.

Now, back to the courtroom.

Thank you, Your Honor.

Dr. Omar, when we last left off, we were talking about the results from the public health department.

Yes.

Neighboring the public health department is the Tox Lab.

My understanding is you had sent a vitreous sample to the Tox Lab for testing there.

It was routine to send vitreous samples to the state toxicology lab for volatile testing,

which would be looking for various alcohols like alcohol that you would ingest, like ethyl alcohol or methanol or other alcohols that could be determined whether that would participate in the cause of death or not.

In vitreous fluid is from the eyes?

That's correct.

Okay.

So in this case, did you get a result back from them if I can get

that report back that would be helpful but my recollection was that the

vitreous fluid was negative for any type of volatiles. Thank you. Yes, it's none detected for ethanol, acetone, isopropanol, or methanol.

Okay.

Is there something important about vitreous versus blood with regards to alcohol?

Is that you aware of?

Well, it's multiple things, actually.

For one thing, it's kind of a sequestered area.

You don't have direct blood flow to that area,

so things just kind of pass through the membranes
