Nine men were shot, at least three of them fatally, in the latest multiple shooting in violence-plagued Detroit, the AP reports. Witnesses said they heard 30 to 40 shots fired as a barbershop on the city's east side was sprayed with bullets, the Detroit Free Press reports. Al's Barbershop was known for gambling, but police, who are looking for at least two suspects and two cars, don't know the motive for the shooting. "I can’t even imagine what would cause this type of violence," the city's police chief says. Detroit's new mayor-elect has vowed to reduce the troubled city's crime rate.
