Maximizing animal wellbeing by minimizing drug-related side effects is a key consideration when choosing pharmaceutical agents for chemical restraint in nonhuman primates. One drug combination that may promote this ideology is butorphanol (27.3 ...

Non-domesticated mammalian animals are anesthetized and immobilized by injecting an effective amount of an anesthetizing and immobilizing drug comprising pharmaceutically active ingredients of butorphanol tartrate, azaperone tartrate and medetomidine hydrochloride (BAM) into the animal from a...

he BAM combination is preferably initially formed as lyophilized powder of the pharmaceutically active ingredients, and then reconstituted before injection as an injectable liquid in the environment of the animal
Mortality resulting from hyperthermia or respiratory depression is usually not an acceptable outcome from any medical or scientific study or examination. Since the animal must be released into the natural environment after completion of the examination or procedure, the animal is likely to be unable to move in response to flight-invoked stimulus or be unable to naturally protect itself if the animal remains partially sedated. Under such circumstances the animal is placed at an unacceptable risk of death or injury from its natural predators or from encountering natural environmental hazards such as cliffs and bodies of water.
Horrifying way to die... really disturbing.
Next question
Can hunters acquire this drug without licence in his state?
If not how did he obtain it?
If he 'lost the bottle en route to B.field , why did he lose it?
Did he just administer a massive dose and throw/drive her somewhere while paralysed?
Is that how she died?
He was quick to blame the mountain lion, as a hunter it's likely he would have known where all the predatory animals hung out..
I'm not sure this is a useful exercise, unlikely her skeleton will retain traces but it does indicate pre-planning.
We need to figure out how he acquired the BAM..
