My question involves criminal law for the state of: California
I saved up my money and bought a non-running vintage motorcycle that had all the correct documents: Title (pink slip) and records of each year's registration, including DMV receipts for payments, all in the original owner's name. Bike has been stored for the last twenty years without registration, so last titled year was 1984. I picked it up last year through his neighbor here in S. California, as the original owner had moved and given it to him.
CHP has this bike's VIN listed as stolen in N. California in 1981, with the name of the person filing the report. This name is different from the original owner's name on all the papers I have.
Also, the original owner paid registration fees (documents I have) for 1982, 1983 and 1984, the three years AFTER this report was filed by a different person in Northern California.
I think there is a transcription error somewhere in the police information. How else, in period, could the original owner register the bike with an active stolen bike report in the CHP files?
I should point out the officer was pretty cool in that after I showed him all the papers, he let me keep the bike, telling me that he would get a hard copy of the report to verify accuracy.
CHP can not locate the person who filed the report and I can't find the original owner. The guy I bought it from offered to make a statement, but I don't think that helps.
My question is: Does an administrative process exist where I can present my information and documents to refute the stolen vehicle report? The CHP insists there is no error. (Actually, the officer said they don't make those kind of mistakes.) They refused to show me the actual report after he got it, but verified the names differ. The officer wants me to turn over the bike.
Or is there a way I can get a copy of the report so I can look for the error?
Any help would be appreciated, as we know I will have to cough up the bike if I can't show there is a mistake.
