They are required to hold the person. The issue becomes if a state is willing to pay to actually extradite the person. They typically aren't unless its a major case. A good example of this is the woman Leticia, an insane woman who had a thread.

That's why you
usually don't see it over a misdemeanor. And yes, they're required to hold and extradite if they have the person, and to some extent even to go pick them up. They aren't required to have a massive manhunt or go to any effort actually to hunt them down, generally.
Considering Melton isn't a fugitive, at present, it's really up to Minnesota whether they want to pursue it, or more likely, use the threat of pursuing it to get him to flip on Nick, the guy they're really interested in. You know Melton is such a gigantic pussy he'd flip in an instant.
States receiving extradition requests are generally really good about pursuing them, because they want their own requests honored (and there are obligations under the Full Faith and Credit Clause), especially when it basically costs them nothing. The issues are really simple if someone tries to challenge it. Is the request from a valid state authority? Is it under an actual statute the authority has jurisdiction over? Is the guy you have actually the guy they're trying to extradite?
That's basically it.
The Constitution does not really leave much wiggle room.
A Person charged in any State with Treason, Felony, or other Crime, who shall flee from Justice, and be found in another State, shall on Demand of the executive Authority of the State from which he fled, be delivered up, to be removed to the State having Jurisdiction of the Crime.
U.S. Const. Art. IV, § 2, cl. 2.
The recipient of the request doesn't get to evaluate the merit of the charges, just that the charging authority itself is valid. The "found in another State" doesn't require any extraordinary effort on the part of the recipient, but if they do have the guy, they are under a near-absolute obligation to turn him over. (Not necessarily immediately since they may have "dibs" on the guy themselves.)
