ITA this reasoning seems unsound. He seems to believe the sheath is probative and relevant to the prosecution's case so he's allowing it in evidence, but he finds essentially that the evidence is insufficient to allow an expert to testify about its significance. Maybe there's more to it than we know. Maybe there's another reason for the ruling. But every time Judge L rules, his reasoning seems shaky, as reported. He does make me nervous the more I see him in action.The following is the most detail I've found quoting Judge Lama explaining his basis for denying the expert.
I'm troubled that he parrots defense attorney IE, and I think his reference to a knife on the counter clearly indicates that he can't make the connection to SM being incapacitated by a tranquilizer would explain why no forensic evidence was recovered or an obvious crime scene in the house (whereas a gunshot or knife would leave evidence).
More important -- Lama seems to completely ignore that BM placed a tranq dart in his hand April 2020 after he first told investigators that he had not used tranquilizers since leaving Indiana. MOO
More expert testimony blocked from Morphew trial
Defense Attorney Iris Eytan began by arguing again that this isn‘t a no-body homicide, but a missing person case.
Eytan said investigators found no syringes in the house containing the tranquilizer in question and that the syringe cap was not in a pair of Morphew’s shorts in the dryer.
She told the judge “The prosecution has made this needle sheath as their claim that Mr. Morphew murdered his wife.” Previous testimony in the case indicated that DNA was found on the tranquilizer cap but that it was not Barry Morphew’s.
Prosecutor Mark Hurlbert said the inference that Morphew used the wildlife tranquilizer on his wife is based on the fact that Morphew admitted he had used the tranquilizer on deer and that there was no blood evidence found in the Morphew home.
Hurlbert said the intent was for the wildlife expert to testify that if the tranquilizer could be used to kill a deer a parallel could be drawn that it could be used to kill a human.
In granting the defense motion to block the expert testimony, Judge Lama said to begin with, there was no trace of the tranquilizer in the house and in a no-body homicide, no direct evidence that Suzanne Morphew was tranquilized. Lama said it would simply be too speculative to allow the prosecution to proceed only on a theory that a tranquilizer was used on Suzanne Morphew.

Lama said similar speculation could be made that if a kitchen knife was found or if the gun was found in the safe, they could be the murder weapons.
Judge Lama clarified that he was not excluding the discovery of the syringe cap in the dryer as part of the prosecution’s evidence, only that the expert testimony was being excluded at trial.
