Presumption of innocence and proof of guilt.
Every person is presumed innocent until proved guilty.
No person shall be convicted of any offense unless his guilt thereof is proved beyond a reasonable doubt. If the issue involved in an affirmative defense, other than insanity, is raised then the State must sustain the burden of proving the defendant guilty beyond a reasonable doubt as to that issue together with all the other elements of the offense. If the affirmative defense of insanity is raised, the defendant bears the burden of proving by clear and convincing evidence his insanity at the time of the offense. P.A. 89-404, eff. Multiple prosecutions for same act.
