At least 14 people were killed and one or more suspects were in custody Wednesday when up to three gunmen on a "mission" barged into a holiday party in a California conference room and unleashed a bloodbath, law enforcement sources told NBC News. The gunman or gunmen fled in a black SUV after the shooting about at 11 a.m. (2 p.m. ET), police said. About 4½ hours later, multiple police cars were involved in a high-speed chase nearby with three people in a dark truck or SUV, law enforcement sources told NBC News. Two of the suspects were shot, the sources said — one was killed and the other was wounded in the chest/NBC News. More here.
