BINGHAMTON, N.Y. - A gunman barricaded the back door of a community center with his car and then opened fire on a room full of immigrants taking a citizenship class Friday, killing 13 people before apparently committing suicide, officials said.
Investigators said they had yet to establish a motive for the massacre, which was at least the fifth deadly mass shooting in the U.S. in the past month alone.
i wonder what is the gunman's motive.
