The 180 day limit is for a Notice of Claim, not a lawsuit. A Notice of Claim is just a letter from you to the state agency or agencies who you intend to sue. You then have 1 year from the date of the incident to file the lawsuit.
The Notice of Claim is a tricky document to write because AZ law requires that you specify the basis of the claim, and state a "sum certain" for which the claim can be settled. This is an amount of money that you would accept instead of suing. This amount must be justified by reference to actual damages and/or other cases with similar facts that have awarded a monetary judgment for the Plaintiff. If the Notice of Claim is not specific enough, the lawsuit may be dismissed for lack of adequate notice to the state.
You generally have 180 days after an incident to initiate a suit against a government entity in Arizona. Hopefully these individuals were prosecuted. If not, contact the county attorneys office and demand these two be held accountable.
