In all likelihood the statutue of limitations for a check that failed to clear for insufficient funds could be based upon a theory of recovery based upon breach of contract, common counts, and possibly farud.In California, the statute of limitations on any of the above theories of recovery would not be more than four (4) years.Trust your intuition regarding the call from the supposed "investigator". Most likely the call is a scam. Have your daughter get as much information from the "investigator" regarding his name, place of employment, mailing address and telephone number. Your daughter should give no personal information about herself.You need to be aware that threatening someone with a criminal matter is an unfair debt collection practice in many states and under federal law.I recommend that you and your daughter report this person to law enforcement.Good luck.
