We may hear medical testimony today in the Derek Chauvin trial -- critical to the state's case as well as the defense's assertion that Chauvin's knee did not cause George Floyd's death. 4/8/21 Thread
First witness today is Dr. Martin Tobin. He is a pulmonologist from Chicago.
Prior to being called, defense attorney Eric Nelson noted that the state will call Hennepin County Medical Examiner Andrew Baker tomorrow, even though it's more common for the ME to testify first then other medical experts afterwards.
Dr. Tobin is a nationally renowned expert on breathing.
If you want to buy Dr. Tobin's "Bible on Mechanical Ventilation," open up your wallet!
Our @LaurenKARE11 is the pool reporter inside the courtroom today. We will fill you in on her notes during the breaks.
Dr. Tobin testifying that unlike most expert witnesses -- he is not getting paid. He was contacted by the state, but said he would do it for free.
Dr. Tobin gives his opinion: "Mr. Floyd died from a low level of oxygen."

He says it caused damage to his brain and caused PEA arrhythmia which stopped his heart. (ER doc already testified about PEA arrhythmia so it matches earlier testimony)
Dr. Tobin testifies that shallow breathing led to the low level of oxygen -- caused by prone position, handcuffs behind back, and knees on neck and back.
There's @LaurenKARE11
Fascinating computer animation of the officers holding down George Floyd.

Dr. Tobin testifies that he believes Derek Chauvin's knee was on Floyd's neck 90% of the time.
Dr. Tobin is testifying that the way the officers manipulated or moved Floyd's handcuffs played a big role.
A visual aid to go with what Dr. Tobin is saying regarding handcuffs -- and what officers are doing with the handcuffs.
Dr. Tobin says you can see Floyd attempt to breathe by lifting shoulder. But it is an "ineffective" way to breathe.

"It's a very poor way of breathing, but it's what you have to do when everything else is failing"
The state is using this with Dr. Tobin to try to show that someone can still speak even if they "can't breathe."
Dr. Tobin now talking about weight distribution and the effect on Floyd's neck.
Another visual aid. This witnesses is checking a lot of the boxes that I know from past interviews jurors like to see and hear when experts are testifying.
Dr. Tobin is addressing studies that say putting weight on someone's back in prone position is not dangerous -- he says these studies are misleading.
Prosecutor Jerry Blackwell reveals in questioning that George Floyd had a paraganglioma tumor. Dr. Tobin testified that it was not meaningful to his death.
Dr. Tobin testified that this moment where George Floyd's leg kicked up and Lane pushed it down -- Floyd was suffering severe brain injury at it was a reflex during fatally low level of oxygen to the brain.
Dr. Tobin just testified that he could see the moment George Floyd died by looking at his face. Blackwell played the Facebook video in slight slo-mo.

"That's the moment the life goes out of his body."
Here is our Youtube link for hte afternoon session:
Nelson in cross-examination just addressed the mixture of drugs - and how the meth and fentanyl counteract each other - meth increasing heartrate.
Nelson is now laying out the defense theory of overdose timeline -- through his question with the witness. That five minutes after ingestion "peak fentanyl respiratory depression" occurs.
New witness is Dr. Daniel S. Isenschmid, NMS Laboratory – Horsham, PA.

That's the same lab where the last witness from yesterday works.
Dr. Isenschmid tested George Floyd's blood at the request of the Hennepin County Medical Examiner.

He said the amount of meth found in Floyd was about the same as taking one dose.
New witness -- Dr. William Smock, Louisville, KY
Dr. Smock: "Mr Floyd died from positional asphyxia, which is a fancy way of saying he died because he had no oxygen left in his body."
Dr. Smock is a police surgeon for the Louisville Police Department.

Prosecutor Jerry Blackwell is questioning him on the "controversial diagnosis" of excited delirium.

Dr. Smock testifies that in his opinion, it is real.

But now saying Floyd did not have it.
"I saw absolutely no evidence of it," Smock said.
Smock testifies that Floyd is not going through a drug overdose.

"That is not a fentanyl overdose. That is someone begging to breathe."
Smock ends direct examination with "As soon as Mr. Floyd is unconscious, he should have been rolled over... you have documentation on the video that an officer couldn't find a pulse... should have rolled over, when couldn't find a pulse CPR should have been started."
In cross-examination -- Eric Nelson asked if the knee was placed on the posterior base of neck -- would not affect diaphragm.

Smock agreed.

The Derek Chauvin trial will resume momentarily with national use of force expert Jody Stiger on the stand for the state. Court ended abruptly yesterday afternoon. Here is my thread for 4/7/21

Testimony is resuming without Judge Cahill mentioning why they quit early yesterday, so perhaps we're reading into it too much?

Here is the youtube link for this morning as Stiger's testimony continues.

Stiger testifies that the knee restraint began at 20:19:19 and ended at 20:28:48 for a total of nine minutes and 29 seconds.

Testimony in Derek Chauvin's trial will resume at 9:15, but first, at 8:30, there is a hearing regarding the witness Morries Hall, who was in the car with George Floyd when approached by officers. 4/6/21 thread
During the testimony of Courteney Ross, George Floyd's girlfriend, she testified that Hall sold Floyd drugs in the days leading up to his death. Hall has filed notice that he will exercise his 5th Amendment rights not to self-incriminate.
In the hearing, Morries Hall is asking Judge Cahill to quash his subpoena so that he will not be called into the courtroom to testify. Hall will appear via Zoom from the Hennepin County Jail, where he is currently being held.

Week two of testimony in the Derek Chauvin trial will get underway at 9:15 morning, possibly including testimony from MPD Chief Medaria Arradondo.

At 8:30, there will be a motion hearing for some legal issues to be discussed.

Actually -- the court docket just slide the start time of the motion hearing to 8:45.
Still waiting on court to begin. Some delays and off-record conversations apparently going on between attorneys and judge.

The trial of former Minneapolis Police Officer Derek Chauvin in the death of George Floyd begins with opening statements this morning in Minneapolis. KARE 11 will broadcast the entire trial live on TV and the web -- here are ways for you to watch.

I expect opening statements to take up much of the morning -- and I also expect the prosecution to begin calling witnesses today. There is also lots of activity around the courthouse and we have several reporters covering all issues.
All 15 jurors showed up, so the last one seated -- a white man in his 20s is dismissed -- the other 14 will make up the 12 jurors and 2 alternates.

Feels like Deja Vu this morning in the Derek Chauvin case, the officer charged with killing George Floyd. Court is scheduled to resume at 8a central with jury selection to start at 9. Here is my thread for 3/9/21 and an article here as a primer. kare11.com/article/news/l…
Last night, Chauvin's attorney Eric Nelson filed a petition for further review to the MN Supreme Court as he said he would. He also filed an opposition to the state's motion for writ of prohibition to the MN Court of Appeals.
What does that mean? We are waiting to hear back from CoA whether they will stop the trial completely while we wait to hear from MN SupCo. The MN SupCo can either agree to take the case or reject it. If they reject it -- the CoA issue becomes irrelevant.
