CONCORD, N.H. — A hearing on the evidence against a New Hampshire man charged with kidnapping a 14-year-old girl from Conway 10 months ago is being postponed until next month.

Prosecutors were scheduled to air their evidence against 34-year-old Nathaniel Kibby at a hearing Tuesday. Lawyers for both sides agreed Friday to postpone that hearing for one month, according to court documents.

Kibby, of Gorham, is charged with kidnapping Abigail Hernandez Oct. 9, sometime after she left Kennett High School in Conway.

Now 15, Hernandez returned home the night of July 20. Investigators have not revealed details of her kidnapping and return.

Kibby was arrested at his trailer July 28.

Meanwhile, a judge has ordered investigators to leave in place the trailer and storage container belonging to a Kibby.

Prosecutors wanted to move the trailer and large storage container from Kibby’s Gorham property to a secure location to ward off damage and intruders. They also cited the costs of posting a 24-hour-guard.

Kibby’s lawyers say the move would deprive them of their chance to investigate.

The judge Friday ruled that the property will remain where it is until the Kibby’s lawyers can photograph it and prepare defense strategy.

Senior Assistant Attorney General Jane Young argued at a hearing Wednesday that investigators are seeking to preserve the evidence by moving it to a more secure location.

Kibby is held on $1 million bail.
