Vet Not to Testify as Expert Witness?
@O.Incandenza sbm bbm Thx for your post. Agreeing in part.*
Vets had no firsthand involvement,
no direct contact w SM, not before or after her disappearance.
From info in AA, afaik -
- neither Vet administered BAM to human.
- no peer-reviewed lit, no controlled studies, no FDA investigational or trial studies, yadda yadda, re BAM use on humans, so there's no scientific basis on which Vet could base expert or professional opinion re BAM effects on humans.***
Even if the Vet had been allowed to speak as an expert witness, imo Vet's opinion about BAM effects on human would be inadmissible. Imo no scientific basis.

* Not sure exactly what part of BAM & dart info from AA, the prosecution wants to put on.
Per AA, LE interviewed two vet's w CO wildlife agency, familiar w BAM animal tranq/similar use on wildlife. Basically, if administered to a human, predicted that BAM would cause sedation, possibly death of human.
Not sure if or how it's relevant.
** These Vets had no firsthand involvement w SM
- did not administer BAM/similar drug to SM, by dart or otherwise.
- did not observe BM or anyone administer BAM/similar drug to SM.
- did not perform or assist in an autopsy on SM, did not run tox/drug tests, did not examine X-rays or scans done p.m., did not examine tissues p.m. under a scope, etc.
*** In AA, one vet said she read of one case where 1/100 of a dose (without specifying quantity - an ounce, gram; milligram, microgram?) was administered to a person.
One anecdote does not constitute scientific evidence.
Thanks for your informative post @al66pine.
I have a real problem with the logic they're using here to disqualify an expert (if they are citing no scientific studies as the basis).

First, I really wouldn't expect any investment in scientific research on using BAM tranq darts on humans but that doesn't mean that there are not anecdotal examples where humans have accidentally or intentionally been shot with tranquilizer dart/sedative that can't be referenced.
For example, what about the 2014 incident where a zookeeper was participating in an emergency drill when he was accidentally shot with a tranquilizer dart (drawn for a 400 lb gorilla). The unexpected reaction here was not the sedation but the allergic reaction to the anesthetic that nearly killed him!
The Rx used with darts would already have scientific data prior to receiving Govt approval. Reportedly, BM was in possession of (expired) BAM Deer Tranquilizer which is a combination of Butorphanol, Azaperone, and Medetomidine where the distributor provides the following:
Butorphanol (butorphanol tartrate) is a synthetically derived opioid agonist-antagonist analgesic of the phenanthrene series, with a potency of about four to seven times that of morphine. In the United States, it is a U.S. Drug Enforcement Administration (DEA) class IV controlled substance. Generally, there is minimal cardiopulmonary depression with its use compared with other opioids and, at lower doses, there is a dose-dependent effect on respiratory depression but then a ceiling is reached and no further respiratory depression occurs.4
Azaperone is a butyrophenone tranquilizer that causes tranquilization and sedation, antiemetic activity, reduced motor activity, and inhibition of CNS catecholamines. Azaperone has been used as a neuroleptic in horses, but some horses develop adverse reactions (eg, sweating, muscle tremors, panic reaction, and CNS excitement) and IV administration has resulted in significant arterial hypotension. Because of these effects, most clinicians avoid the use of this drug in equines.
Medetomidine (medetomidine hydrochloride), used alone and in combination with other drugs, has been shown to be useful for anesthesia and immobilization in zoo animals.1,4 Medetomidine is an α-2-adrenoreceptor agonist with sedative and analgesic properties. It is used by veterinarians as both a surgical anesthetic and analgesic. The pharmacological restraint and pain relief provided by medetomidine facilitates handling and aids in the conduct of diagnostic or therapeutic procedures.4
IMO, just reading the manufacturer's description above is sufficient to infer the possible reaction by a petite woman already taking certain other Rx.
And better yet -- I don't think it prejudicial for the Court to see a demo video of the product in use-- exactly as intended. (And wouldn't BM enjoy that)!
IMO, BM already opened the door for the jurors to learn what happens to a deer when he shot it with BAM!
I'm appalled that Judge Lama has opined that it would simply be too speculative to allow the prosecution to proceed only on a theory that a tranquilizer was used on Suzanne Morphew, and denied the Vet from giving evidence. MOO
BAM Deer Tranquilizer
Zoo: Keeper Accidentally Shot With Tranquilizer Was NOT In Gorilla Suit
ETA: It seems to me Judge Lama thinks the theory where BM used a BAM dart on SM is too speculative because the BAM was inside the garage and not the house??
