*As noted in the text above, Lanza also fatally shot his mother in their Connecticut home. However,
according to the NYPD’s classification methodology, targeted attacks that occur prior to the active
shooting event are not included as a separate location and do not add to the active shooter casualty count.
Moreover, according to NYPD’s classification methodology, attackers that return to a school in which they
were once a student are classified as having an “academic” relationship to their closest victim. This
classification methodology is consistent throughout the report.
