A.R.S. § 13-105(10)(c) defines 'recklessly' as 'with respect to a result or to a circumstance described by a statute defining an offense, that a person is aware of and consciously disregards a substantial and unjustifiable risk that the result will occur or that the circumstance exists. The risk must be of such nature and degree that disregard of such risk constitutes a gross deviation from the standard of conduct that a reasonable person would observe in the situation. A person who creates such a risk but who is unaware of such risk solely by reason of voluntary intoxication also acts recklessly with respect to such risk.'
