Good morning. A 16-year-old shooter opened fire at an elementary school in Bend, Oregon, on Thursday, killing three children and a teacher, before he was shot dead by a community member. The children killed were five, eight and 11, officials said. The gunman, who was a Bend resident, has not been publicly identified.

Parents hugged, kissed and held their children’s hands as they walked to their cars, with some bringing along favorite stuffed animals or other comfort items from home. Here is what we know so far.
