The number of serious crimes reported to the Kootenai County Sheriff's Department last year grew by more than 10 percent even as the department's staffing levels continue to lag behind other state law enforcement agencies. "Group A" offenses, including crimes like murder, manslaughter, rape, assault, kidnapping, extortion and drug charges, grew by 10.5 percent in 2007, said Undersheriff Tad Leach. Total calls for service grew by almost 18 percent compared to 2006.
