(AP) – The gunman who killed 19 children and two teachers at an elementary school in Uvalde, Texas left so many hints that he was violent and obsessed with notoriety that former classmates began calling him “school shooter.” He was bullied in fourth grade in the same classroom where the May 24 massacre occurred. And to prepare for it, he elicited details about the school from a young relative and collected articles about the Buffalo, New York supermarket shooting. A state investigative report that highlighted law enforcement’s bungled response to the mass shooting at Robb Elementary School has also provided the most in-depth account to date about missed red flags and possible motivations surrounding 18-year-old Salvador Ramos.
