The names of the 19 children and two adults killed in Tuesday's mass shooting at a Texas elementary school are starting to come out, as are other details of the massacre. The gunman, who was killed, was identified as a local 18-year-old, and a state senator says "the first thing he did on his 18th birthday" was buy the two military-style rifles he used in the shooting, Fox 7 reports. He shot his grandmother, with whom he apparently lived, after an argument, Click2Houston reports (reports differ on whether she survived) before driving to Uvalde's Robb Elementary School. He crashed his car through a barrier and into a ditch, shot at police officers who responded, then made his way into the school. "At that point as he made entry he began shooting children, teachers, anybody that was in his way; he was shooting people that were in front of him," a lieutenant says. The AP reports he went from classroom to classroom shooting. More:
