(CBS/WBZ/AP) TEWARTSTOWN, N.H.- Authorities say the autopsy on the body of Celina Cass, which was recovered Monday morning from the Connecticut River, did not reveal what killed the 11-year-old New Hampshire girl.
The autopsy was conducted Tuesday but didn't determine a cause of death and further study is required, Senior Assistant Attorney General Jane Young said.
Meanwhile, the girl's hometown is expected to move forward with its annual children's festival called Stewartstown Days. It's scheduled for Friday and Saturday.
Stewartstown residents had considered canceling it but they are now dedicating the event to her memory.
Celina's body was found near a hydroelectric dam that spans the Connecticut River between Stewartstown and Canaan, Vermont., Essex County state attorney Vincent Illuzzi said.
Celina was last seen in her house a week ago, Monday, July 25, at her computer.
The FBI has offered a $25,000 reward in the case.
Anyone with information is asked to call the state police at 603-846-3333.
