There is a way to expunge arrests and, maybe convictions but I think that the Legislature did some kind of review of this many years ago. I do not know what the status of this process is. I believe the result of the process is that you can answer "no" to the question, "Have you ever been arrested.". Nothing you can do about search engines and newspapers though.

Good luck. I don't really like marks for getting arrested without conviction as it results in reputational damage.
