There aren't that many shore divers in Minnesota, and there aren't that many dive sites. I'm glad for the heads up, if nothing else. From the summary on the Sheriff's web site, he's believed to be "off the grid" as you put it, and they'll probably have a hell of a time smoking him out unless he gets arrested again or the sheriff gets lucky.
Well, he's a convicted felon, and the crimes he was convicted of weren't exactly speeding tickets. I'm not going to go looking for him. OTOH if I see someone matching his description I may make a phone call.
It's not. He's still on the department's most-wanted list, which is updated regularly.
He is most certainly off the grid. LEO's have a watch on credit cards and everything else about him. If that has not found him, there is no reason that this guy would live among those that now him and could point to him. The very nature of this type of request raises a big red flag. This is the actions of bounty hunters or private investigators. I suppose I would look at this differently if the OP had the link to the sherrifs website and the guy was known to be in a certain area. All dive shops would have already been put on notice of his possible presence. To stay off the grid is difficult. Now adays that means appearance change and identity change which makes SB once again useless to assist in finding this guy.
