Police investigate manifesto reportedly left by girl who killed two in school shooting

Fifteen-year-old pupil at Abundant Life school in Madison killed teacher and student and wounded six others

The 15-year-old girl who police say killed a teacher, a student and wounded six others before dying by suicide at a school in Madison, Wisconsin, reportedly left a manifesto that investigators are now reviewing.

Police identified Natalie Rupnow – who also went by the name Sophie – as the shooter late on Monday. A law enforcement source told CNN that Rupnow “had been dealing with problems and expressed some of those in writings, which they are now reviewing”.
