WEST STEWARTSTOWN, N.H.  — The reward for information leading to an arrest in the death of Celina Cass has grown to more than $30,000.

The body of the 11-year-old West Stewartstown girl was found in the Connecticut River five weeks ago, not far from her home.

Authorities tell WMUR-TV that recent contributions have bumped the reward to $30,665 for information leading to the arrest and prosecution of anyone involved in her death.

The FBI supplied that bulk of the donation, $25,000.

The death is being called suspicious. An autopsy failed to pinpoint the cause and manner of her death, but investigators have yet to call it a homicide.
