Thanks for the replies.
Yes it's a state warrant from New York. Subject escaped from a maximum security state pen (Clinton) where he was serving time for murder. Subject has three previous escapes on his record. Subject has been a model citizen since moving to New Hampshire and has no New Hampshire warrants.
You can actually ignore the escape warrant. He is an inmate, subject to arrest on that. This covers the situation before the prison has a chance to charge someone with escape. What would happen in this situation is US Marshall would contact town police. Town police would swear out an arrest warrant for fugitive from justice. They would then go to his house on that arrest warrant and arrest him on that. Other than the US Marshall being there, this would be just like an arrest for any other crime.
Remember, without a valid NH arrest warrant, no one has any authority in this type of situation to take him into custody (this is very different from stopping him in a vehicle and identifying him). The statute is RSA 612:2 http://www.gencourt.state.nh.us/rsa/html/lix/612/612-mrg.htm
Would there be a point in fighting extradition? He knows he's going back, and although he has a long history of being uncooperative, he is cooperative at this point. He does not deny that he is who they are looking for. The only advantage I can see in fighting extradition would be more time in NH where his family is, but he's not keen on seeing them from behind bars anyway.
Seriously, NH has better jails than NY. A lot less hard core. Other than that, no reason.
Police station is in the town hall. This is a tiny town northwest of Concord (think one of the hill towns, Jim.) They have a holding cell in the basement, but are not set up for long term confinement.
Police stations aren't set up for long-term confinement anywhere in NH. You're probably looking at either Grafton or Merrimack County. Grafton's county seat and jail is in Haverhill, NH (not pronounced like it reads -- it's only two syllables). Lots of towns there fit your description. You might also want to look at New London, whose police department was in the town hall (town offices on the first floor, police in the basement). Police provided secure confinement through a big ring set in the floor and ankle shackle. This may well have changed as it's over 10 years since I went there. New London is Merrimack County whose county Hilton is in Boscawen, NH. Nice place, newly rebuilt.
So it's looking like he would be arrested by the original marshals, who would go back to where they came from, he'd be transferred to the county lockup, have a hearing in the morning, and get handed back over to the USMS for transport to New York, not necessarily by plane. Or driven by New Hampshire to the border closest to New York and handed over to New York? How much paperwork is my local police chief looking at? Is the guy in his custody, officially, between the time the marshals pick him up and he gets handed off to the county? Or is he in NH state custody? Would he be fingerprinted at the local PD? Is his lawyer going to need to come up from New York for this?
He is in custody of the arresting town, acting as an agent for the State of New Hampshire. His actual body would be in the county jail, although he stands a serious probability (based on his record) of being transferred to the SHU (Secure Housing Unit -- maximum security) of the NH State Prison (Concord, NH). New Hampshire holds him on the fugitive from justice charge until he is transferred to New York, either direct or through the US Marshall. If he is driven, it would be NY state prison officials who pick him up. He would be fingerprinted and processed at the town, and then when he goes to the county jail.
His NY lawyer would probably not show up, unless he is a private pay. When the case comes up in front of the judge, the judge will grab a local attorney who's in the courtroom, and volunteer him/her. Bright side for the attorney is this requires absolutely no skill.
Paperwork is no worse than for any arrest. Most of the paperwork would actually be generated by the NH Attorney General and be photocopies of what NY faxes over.
So when he gets to NY, is there a sentencing hearing on the escape charge and would that be up in Clinton county? He'll plead no contest to the escape, does that mean they can skip the formal hearing? Clinton doesn't want him back, he's off to Attica at this point. Persistent Felony Offender, looking at life without possibility of parole.
Which means he might immediately go to Attica, which is more likely to involve a plane trip. In NH, he would be charged with a Class B felony, escape, which is 3 - 7 years in prison if you get the whole thing. To be sentenced for additional time, he would have to go to court and be sentenced by a judge. Even inmates with life sentences are charged and tried for escape.
You know, all of this is like one chapter in my novel, but I really want to get it right.
