STEWARTSTOWN, N.H. --
Dozens of investigators from state and federal agencies are working out of a school in northern New Hampshire in their efforts to find a missing 11-year-old girl.
Police went door to door in Stewartstown on Thursday asking residents for any information they might have about the disappearance of Celina Cass, and townspeople are passing out fliers. The girl had last been seen when she went to bed Monday night.
Jane Young of the New Hampshire attorney general's office says investigators are leaving no stone unturned. Across the border, the Royal Canadian Mounted Police in Quebec were alerted to the girl's disappearance, but there had been no sightings as of late Thursday.
Police have said that there's no indication she ran away and there were no signs of a struggle.
