( CNN ) -- Investigators searching for clues in the Abigail Hernandez kidnapping case reportedly have a new focus : a storage unit on the suspect 's property . That 's where the teenager was held captive , sources told New England Cable News . The rust-colored storage container , which some neighbors referred to as an above-ground bunker , was surrounded by crime scene tape on the day of suspect Nathaniel E. Kibby 's arrest , CNN affiliate WMUR reported . The New Hampshire Attorney General 's office declined to comment on those reports to CNN . Assistant Attorney General Jane Hall said arrest and search warrants in the case will remain sealed for now . A probable cause hearing is scheduled for August 12 , when evidence might be presented detailing how the teenager was found . `` It 's remarkable how well she 's doing , '' Hall said . `` Just to be able to endure what she did ... under any set of circumstances . '' Hernandez , 15 , sat just steps away from her alleged kidnapper at an arraignment hearing on Tuesday . Kibby , 34 , was arrested Monday and charged with one count of felony kidnapping for allegedly confining Hernandez on October 9 `` with a purpose to commit an offense against her , '' according to prosecutors . He was ordered held on $ 1 million bail . His lawyer , Jesse Friedman , did not enter a plea at Tuesday 's arraignment hearing , arguing that the charge against Kibby is unclear because prosecutors have sealed the arrest warrant . `` I have no idea what they 're alluding to , '' Friedman said in court . The judge denied Friedman 's motion to unseal the warrant . Hernandez returned to her home last week , more than nine months after she went missing on the way home from school . Hernandez 's case drew national attention when the then 14-year-old girl went missing last fall . But the mystery surrounding her disappearance only deepened when authorities and her family revealed few details upon her return last Sunday . Investigators said Hernandez provided police with details of her kidnapping that were `` sufficient '' to warrant Kibby 's arrest Monday . In a statement Friday , her family said they were cooperating with law enforcement and `` trying to focus on the peace and joy of the moment of Abby 's return . '' `` Right now , Abby is resting , extremely tired and in deteriorated health , and has lost a lot of weight . She is working to build her strength back and we hope soon she will be back on solid foods , '' her family said . `` We appreciate people 's vigilance as they share the sketch photo that law enforcement has distributed and we hope that very soon this long , long ordeal can come to some closure . '' On Monday , Hernandez thanked those who searched for her while she was missing . `` I wish that I could personally thank everyone who looked for me . My gratitude is beyond words , '' she said 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 . Thank you all for the welcome home . '' CNN 's Catherine E. Shoichet and Marina Carver contributed to this report .
