An as-yet unidentified school shooter attacked Reynolds High School in Portland, Oregon today, killing at least one student. It was the 74th school shooting since Adam Lanza's infamous assault on Sandy Hook Elementary School in Newtown, Connecticut — and, as this map shows, they've happened all over the country.
