In State v. Jackson, 208 Ariz. 56, 90 P.3d 793 (App. 2004), the Court concluded "the seven-year limitation period under 13-107(B) begins 'when the authorities know or should know in the exercise of reasonable diligence that there is probable cause to believe a criminal offense has been committed.'" 208 Ariz. 56, P30, 90 P.3d at 802.
The Court further stated "probable cause exists 'when reasonably trustworthy information and circumstance would lead a person of reasonable caution to believe that a suspect has committed an offense.'" Id. P31.
