It has been reported, and then disputed, that Lanza’s mother was a school teacher. At least twelve shooters have had family members who were teachers, professors, or had other positions in education.
Also, of the eight family members killed by the five shooters just mentioned, four of the eight had been teachers.
Jeffrey Weise, who committed the rampage in Red Lake, Minnesota, in 2005, first killed his grandfather and the grandfather’s girlfriend.
Other shooters have killed family members, and other shooters have been adults who attacked elementary schools, but no previous shooter has done both. Nonetheless, it may be useful to compare Lanza’s attack to the rampages it most resembles.Luke Woodham, in 1997 in Pearl, Mississippi, killed his mother.In 1998, in Springfield, Oregon, Kip Kinkel killed both his parents.Psychotic shooters are people struggling with schizophrenia (or sometimes schizotypal personality disorder).Their symptoms include auditory hallucinations (i.e., hearing voices), delusions of grandeur and/or paranoid delusions, and severely impaired social functioning.
