List of rampage killers (workplace killings)

This section of the list of rampage killers contains those mass murders where the perpetrators predominantly targeted their (former) co-workers.

A rampage killer has been defined as follows:

A rampage involves the (attempted) killing of multiple persons least partly in public space by a single physically present perpetrator using (potentially) deadly weapons in a single event without any cooling-off period.

This list arbitrarily limits the scope of the subject to workplace rampage killings that meet the following criteria:

  1. 6 or more dead
  2. at least 4 people killed and least 10 victims overall (dead plus injured)
  3. at least 2 people killed and least 12 victims overall (dead plus injured)

In all cases, the perpetrator(s) shall not be counted among those killed or injured.

All abbreviations used in the tables are explained below.
