Orlando Harris, the gunman who killed a student and teacher at a south St. Louis high school before police killed him Monday, had about 600 rounds of ammunition and left behind handwritten notes about being a loner with no social life, which he called the perfect storm for a mass shooting. St. Louis Interim Police Chief Michael Sack disclosed a passage from a notebook belonging to Harris, 19. He left the notebook in the car he drove to Central Visual and Performing Arts High School. “I don’t have any friends, I don’t have any family,” it read. “I’ve never had a girlfriend. I’ve never had a social life. I’ve been an isolated loner my entire life. This was the perfect storm for a mass shooter.”
Harris, a former student, broke into the high school Monday morning armed with an AR-15 rifle. Police confronted him inside the school and shot and killed him, 14 minutes after police received the first call for an “active shooter," reports the St. Louis Post-Dispatch. Sack said the note gives a glimpse into the gunman’s mind. “He feels isolated, he feels alone,” Sack said. “Quite possibly angry and resentful of others who have, it appeared to him, to have healthy relationships, so a desire to lash out.” Sack urged people to speak up if they notice someone who appears to be suffering from a mental illness or distress and talks about buying firearms or causing harm.
