I think that if a tranquilizer gun was used, the article would have said that.
I think the usual route to administer a drug to incapacitate a person would be oral. Like when rapists put what are called "roofies" into the drink of a person and then sexually assault the victim while they are unconscious.
Some murders are committed via injections. Claus von Bulow injected his wife with insulin. Killer nurses can inject poison via an IV setup or via an injection. But in those cases the victim was already likely sedated and supine.
Some murderers, largely female as I recall, use poison to kill their victims. Such poison is usually administered orally, hidden in food.
I just have never ever heard of a single case where the murderer used an animal tranquilizing gun to fire a dart loaded with drugs into a heathy person, then wait for the 5 to 10 minutes it would take for the drug to take effect, and then murder the unconscious victim. It seems so unusual a method that I question the prosecution's theory that this is what happened. And the evidence is based on a needle sheath found in the dryer?
Further, I don't believe the prosecution had presented any evidence that BM had purchased incapacitating drugs that could be used in a tranquilizer gun. If the prosecution is correct and this is what indeed BM did, perhaps he purchased Fentanyl on the black market and used that?
Also I don't recall that LE seized BMs tranquilizing gun as evidence. Did they?
The idea that a man would use a tranquilizing gun for animals for the first time in the history of crime to commit a murder against his wife of 26 years, and the mother of his two children--it just doesn't seem likely to me.
Also, doesn't anyone have any info on if BM has a history of arrests? For domestic abuse or for anything? Seems difficult to believe a guy that age would chose murder of his wife as his first crime.
If it was just the needle sheath in the dryer, then that would be weak evidence. Fortunately, that wasn't it at all.
Barry initially claimed that he had never fired a tranquilizer gun in Colorado. He also couldn't remember the name of the reversal agent.
Later on, Barry did what killers frequently do, he changed his story, and admitted to a lesser crime. He claimed that he had shot two deer with tranquilizer darts in April, and sawed off their antlers.
There are several problems with this:
One, deer don't have antlers that time of year (or ones you'd want as trophies).
Secondly, what?!
Third, the tranquilizer gun in his garage would have required a modification in order to fire (duct tape).
Fourth, he admitted to possibly throwing away tranquilizer materials on the very day Suzanne disappeared. Amazing!
Fifth, there's just no way something that large could have gone undetected for any length of time inside that dryer (giving Barry the insane benefit of the doubt about April).
Crazy as it is, Barry is telling us that the tranquilizer dart is relevant. If he used a gun, it's missing. I'm also open to it being done manually.
Although there is plenty of precedent for killers injecting their victims with something like succinylcholine, which basically paralyzes you and can stop breathing, I'm not sure about precedent for the drug Barry apparently used.
Then again, most people don't have access to a controlled substance like that, nor are they as obsessed with hunting as Barry.
Page 120. Equal parts poetic and pathetic:
Barry said, "All I have now is my hunting. That's all I have. And I've done it since I was seven years old. So, if I got to live this life without her, I at least want my hunting.
