Investigators took people in for questioning Thursday in the shootings of two police officers overnight in Ferguson, Missouri. Sgt. Brian Schellman, a spokesman for St. Louis County police, confirmed the questioning to NBC News, though no arrests have been made. A SWAT team converged on a house in Ferguson as part of the investigation, he said. The two officers were released from the hospital before 9 a.m., less than nine hours after they were shot outside Ferguson police headquarters. Police Chief Jon Belmar of the county police said that both were lucky to be alive. "We could have buried two police officers next week over this," he told reporters. Meanwhile, Attorney General Eric Holder in a statement called the shootings inexcusable and repugnant."
