That is the court records so they should be up to date.
Mr. Driessen is a former Deputy DA in Orange County with over 8 years of criminal law experience. Nothing stated on this site shall in anyway be construed as legal advice, or as creating any attorney client relationship.

The Arizona Supreme Court public access site is generally the best site for up to date court cases. As my collegues mentioned, some of the city/municipal courts have their own websites that you can research as well.
The Supreme Court website is usually updated quite regularly, so the information is likely up-to-date. However, the Supreme Court Public Access to Court Information website does not have information from the Pima County Justice Courts or Superior Court. So, if the person was cited for a misdemeanor in Justice Court or a felony in the the Pima County Superior Court, you would need to go to the websites for those courts to get any information on the case. An easy web search should direct you to the proper websites.
