My son received a letter in the mail the beginning of Feb stating that "on or about" 7/20 a complaint was filed for assault, theft under $400.00 and defrauding an innkeeper. No other information other than he must appear in court 2/22 or a warrant may be issued for his arrest. He has no idea what this is about. He was not in the city who is charging him "on or about" 7/20. Doesn't he have the right to know more specifics of these charges before appearing in court for the arraignment?
