ST. LOUIS _ The same scenes play out time and again for St. Louis police Lt. Scott Aubuchon's homicide detectives when they arrive to investigate another death in the city: yellow police tape, the wails of family and evidence technicians scouring for bullet casings.
Aubuchon's team is struggling to keep up as the city contends with a homicide rate that, by year's end, likely will be the worst in at least a half-century.
