Federal authorities announced racketeering and other charges Wednesday against 45 members or associates of two major Minneapolis street gangs for crimes including seven homicides, plus numerous drug trafficking and firearms violations. The suspect in a mass shooting in Atlanta that left one woman dead and four others wounded has been charged with one count of murder and four counts of aggravated assault, Fulton County Jail records show. Two 10-year-olds are among 300 children who worked at McDonald’s restaurants illegally, a Labor Department investigation of franchisees in Kentucky found.
