You have to file a complaint with the local governmental entity within six (6) months of the incident, in order to preserve a claim at the state level. For a federal claim, you, generally, have two (2) years. You/They need to contact a California civil rights attorney ASAP to further discuss the matter.
I agree with all of the attorneys above regarding the statute of limitation to file a claim against the city. The claim forms are usually online.
Consult a civil rights attorney immediately but judging from the facts provided. Here's a problem/missing element: what are that person's damages? He or she will have trouble proving dishonesty and damages. Dishonesty and conspiracy are very difficult to prove. You can file a claim, but it'll be hard to get a civil rights attorney to work on your case. It's not easy going against the city/county or state.
Good-luck though. :)
