Three juveniles were recently charged in federal court for making bomb threats to Wolf Point High School, authorities said. The juveniles allegedly made bomb threats to Wolf Point High School in December and January. Their names have not been released since federal law prohibits the release of the names of juveniles charged in U.S. District Court. The investigation was conducted by the Wolf Point police, Roosevelt County sheriff's deputies, Fort Peck tribal police and the FBI. Leroy Chavez, a Glasgow-based FBI agent investigating the threats, talked to students at the school and emphasized the seriousness of the crime. Sherry Matteucci, U.S. attorney for Montana, said the case would be prosecuted vigorously.
