WASHINGTON (AP) — A law enforcement official says that 20-year-old Adam Lanza, suspect in the Connecticut school shootings, killed his mother at their home Friday and then drove his mother's car to the school where he went on a deadly rampage.
Adam Lanza's mother, Nancy, was a teacher at the school, said the law enforcement official.
One of the officials said earlier Friday that a girlfriend of one of the Lanza brothers and another friend were missing in New Jersey. Subsequently, the third official said police had talked with the girlfriend. One of the friends had to be reached in California, so it took some time.
