Uh-huh. The latest now on the innew Hampshire teenager missing for nine months, suddenly returned home last week. A suspect has been arrested on kidnapping charges expected in court this afternoon. ABC's Ryan submit is tracking the case from Conway, new Hampshire. Good morning, Ryan. Reporter: Good morning, George. Today the man accused of kidnapping Abigail Hernandez is expected to be arraigned in this courthouse. Now, yesterday, he was arrested at a local trailer park. Police told residents to stay inside as a S.W.A.T. Team descended in to capture the man that they say is a central figure in the teen's nine-month disappearance. This morning, 34-year-old Nathaniel Kibby is sitting in jail accused of felony kidnapping in the disappearance of Abigail Hernandez. Prosecutors saying he confined the now 15-year-old girl with the purpose of committing an offense against her. What offense is still unknown. According to ABC affiliate WMUR, Kibby kept a storage container that some are referring to as an above ground bunker in his backyard. I haven't noticed anything unusual. Reporter: Overnight Hernandez who disappeared nine months ago saying in a statement" it's an incredible feeling to be home and I believe in my heart that your hopes and prayers played a major role in my release." Officials say a traumatized Hernandez who family says is malnourished and unable to eat solid foods is now helping investigators piece together clues to understand where she has been. His neighbors are shocked wondering if Abby was held in that storage container all along. I would hope that she can't be that close and nobody knew it. Reporter: Those clues leading them straight to Kibby in the town of Gorham 35 miles away from her home. Hernandez initially thought to be a runaway until she received a letter from her in November. It was numbing for the first maybe three weeks, four weeks and then I received a letter and it was like exhilarating. Someone may not be manipulating her and her safety is still in question. Reporter: Last Sunday after nine long months of searching, Hernandez returned home. A family friend was with Abby and her mother when they learned of his arrest. Now they can finally get to some closure. Now they just get to be the Hernandez family again and they haven't had that for a long time. Police still aren't revealing the details of the alleged kidnapping or how Abigail Hernandez came to be reunited with her family but more should be revealed today or at the press conference scheduled to take place later today. George. Okay, rooib, thanks. Our chief legal affairs anchor Dan Abrams and these kidnapping charges would hold even in Abigail originally chose to go with the guy. We don't know that's the case but it wouldn't matter. Under the law in New Hampshire, if he knowingly took away, enticed away, even concealed a child under the age of 18 who he's not related to to keep that child away from her parents, that would be the crime of kidnapping. But it could be Rell vent if he brought her back. That's right. If, if, and it's a big if, if he brought her back in a safe place and -- and this is the biggest if there wasn't serious bodily injury -- That would be the big debate. If that were the case, returns her to a safe place and no serious bodily injury could be talking about taking it from a class a felony which would be 7 1/2 to 15 years to a class B felony of 3 1/2 to 7 years so the law is specifically designed to entice someone who engages in a kidnapping to return someone safely to their home. Again we don't know and based on the condition she's in I think there would be a real question as to whether there was no serious bodily injury. The details that come out today could be key.
