STEWARTSTOWN, N.H. (AP) - The FBI is offering a $25,000 reward for information leading to an 11-year-old northern New Hampshire girl who's been missing for five days.
 
FBI agent Kieran Ramsey said at a Saturday afternoon news conference that the reward would also cover information leading to the arrest and prosecution of anyone responsible for Celina Cass' disappearance.
 
Jane Young of the state attorney general's office says a community member was adding a $5,000 reward.
 
Celina was last seen Monday night at her home computer in Stewartstown. Investigators have knocked on about 300 doors in the area and in neighboring Vermont, with plans to continue.
 
Police have said there is no indication Celina ran away or that someone took her.
