CONCORD, N.H. — New Hampshire authorities say the death of an 11-year-old girl whose body was found in a river last month was a homicide.
Investigators say they also know how what caused Celina Cass’ death. But they aren’t making it public, because they say doing so could harm the integrity of the investigation.
Cass was reported missing July 26. Her body was found a week later in the Connecticut River, not far from her West Stewartstown home.
A reward has been offered for information leading to an arrest.
The attorney general’s office said Thursday that the cause of death was determined through information gleaned from the investigation and toxicology tests.
