Teachers describe close calls with St. Louis school shooter during deadly rampage: "He let me go"

Two teachers recounted near-miss confrontations with a teen gunman who broke into a St. Louis high school Monday morning, fatally shooting a teacher and a teenage girl, and wounding seven others before police killed him in an exchange of gunfire.  

Police Chief Michael Sack identified the shooter as 19-year-old Orlando Harris, who graduated from the school last year. Sack said the motive was still under investigation but "there's suspicions that there may be some mental illness that he's experiencing."

Ashley Rench told The Associated Press she was teaching advanced algebra to sophomores when she heard a loud bang. Then the school intercom announced, "Miles Davis is in the building."
