§ 130.05  NEGLIGENCE.
   A person is negligent, or acts negligently, when that person fails to be aware of a substantial and unjustifiable risk that circumstances exist or a result will follow, described by the statute defining the offense, and that failure constitutes a substantial deviation from the standard of care that a reasonable person would exercise in the situation.
