Friends and witnesses have identified the owner of the dance studio that was the target of a horrific mass shooting late Saturday night as one of the victims who gave his life during what has been described as one final act of selflessness. A man who identified himself as a friend of Ming Wei Ma told CBS News that Ma was among the victims of the attack, which left 10 people dead and another 10 wounded. According to Chen, “he was the first to rush to try to stop the shooter.” Chen said: “He was just caring, and other first, people first kind of person.” Police have not officially identified the deceased.
