Some info on Stanley Burroughs

He wrote a second book: "Healing for the Age of Enlightenment"

In 1984 he went to court and was convicted of second degree felony murder in regards to a patient who had leukemia and who died after he prescribed him to do the Lemonade Diet for 30 days and colour therapy and aksed him not to see a regular MD:

quote
Procedure: Trial court ruled that the felony of unlicensed practice was inherently dangerous to human life and the felony-murder rule applies. Trial court instructed the jury that if the death resulted directly from the commission of the felony, then the homicide was felony murder in the second degree. D was convicted of felony practicing medicine without a license and second degree felony murder.

This conviction was later reversed.

In order to determine whether the felony is inherently dangerous to human life, Ct. should consider the elements of the offense and not the facts involved in the case. The elements involved in the offense of practicing medicine without medicine do not meet the standards of “inherently dangerous to human life” doctrine. Next, the ct. should consider the factors that elevate the unlicensed practice of medicine to a felony. The statute dealing with this area does not necessarily include great danger to human life. Therefore, a broken arm resulting from such offense will be considered a felony. So the trial ct. erred in its reasoning by considering the felony involved in this case to be inherently dangerous to human life and then applying the felony-murder rule. The felony-murder rules purpose of deterrence will not be served if this rule is applied to the defendant in the current case. Defendant’s second degree murder conviction reversed.

In 1984, when he went to court he was already 77 years old - I couldn't find when he passed away.
