(a) Criminal homicide constitutes murder when: (1) it is committed intentionally or knowingly; or (2) it is committed recklessly under circumstances manifesting extreme indifference to the value of human life; or (3) death is directly caused by the illegal use of a Schedule I Controlled Substance, defined by Chapter 67 of this Title, to any person. Any person who knowingly or willingly transfers or sells any Schedule I Controlled Substance to a person over the age of eighteen (18) years old in violation of the provisions of Chapter 67 of this Title, and such controlled substance directly causes the death of such person, is guilty of murder. This Section shall not apply to health care professionals and pharmacists in the legitimate practice of the healing arts. (b) Murder is a felony of the first degree, but a person convicted of murder shall be sentenced to life imprisonment notwithstanding any other provision of law; provided, however, that any person convicted of murder shall be eligible for parole after serving fifteen (15) years as provided in § 80.72 of this Title and no part of said sentence shall be suspended; provided, further, that any person convicted of murder shall also not be eligible for work release or educational programs outside the confines of prison.
