(a) 
For purposes of this section, a person acts with criminal negligence, or is criminally negligent, with respect to circumstances surrounding his conduct or the result of his conduct, when he ought to be aware of a substantial and unjustifiable risk that the circumstances exist or the result will occur. The risk must be of such a nature and degree that the failure to perceive it constitutes a gross deviation from the standard of care that an ordinary person would exercise under all the circumstances as viewed from the actor’s standpoint.
(b) 
A person commits the offense of failure to supervise a child if such person is the parent of a child under eighteen (18) years of age, or such person is the lawful guardian of a child under eighteen (18) years of age, and:
(1) 
Such person, with criminal negligence, allows such person’s residential property, commercial property or rented premises to be used for a gathering of individuals under the age of twenty-one (21) years of age, and where, at such gathering, alcohol or other illegal controlled substances are served, consumed, ingested or otherwise used by said individuals under the age of twenty-one (21) years of age.
(2) 
Such person, with criminal negligence, allows said child to be in possession of (i) stolen property, or (ii) a controlled substance, as that term is defined under State law, and where said child does not have a legal prescription for said controlled substance.
(c) 
It is an affirmative defense to an offense under this section if the person took reasonable steps to control the conduct of the child at the time the person is alleged to have committed the offense of failure to supervise a child.
(d) 
Any person or entity violating any of the provisions of this section shall be deemed guilty of a misdemeanor, and upon conviction thereof may be fined as provided in section 1.01.009 of this code.
