3 strikes law

I cannot advise you on the question of reporting him or not, but I can say that based upon the facts you have provided, the three strikes law is not in play. The three strikes law does not apply to all felonies, and neither theft, nor ID theft are "strikes" in Washington. These may be felonies however, and upon a conviction, he may end up being a convicted felon which does have it's own implications. He could also be prosecuted for a misdemeanor, but the ID theft is a felony if the state chose to charge it as such. There may be other reason to file such a report, but you will want to be sure that is what you want to do. I would suggest calling a lawyer in your area to discuss the implication of such, for both him and yourself to be sure. Often these cases are better left for the family to deal with, sometimes they are not. I wish you the best of luck.
