Weston Halsne, a grade five student who was attending a mass service with his classmates, was present when 23-year-old assailant Robin Westman opened fire on Annunciation Catholic Church in Minnesota Wednesday – killing two children and wounding 17 others, before taking their own life. Halsne, 10, says friend Victor shielded him from the shooter, by jumping on top of him and taking a bullet to the back.
