Harry Kecinski was a German national listed in historical records of rampage killers in Europe. At the time of the killings, he was reported to be 44 years old, placing his birth year in 1970. Records categorise him as the perpetrator of a mass murder that occurred in Fahrdorf, Schleswig‑Holstein (then West Germany) on 20 April 1970.

On 20 April 1970, in the municipality of Fahrdorf in Schleswig‑Holstein, West Germany, Harry Kecinski carried out a mass shooting that resulted in multiple deaths. He is listed in compilations of rampage killers as having killed his own family members and then taken his own life by suicide at the scene of the crime.

Records that summarise mass shootings in Germany describe the Fahrdorf incident of 20 April 1970 as involving a man who killed nine people and then committed suicide. The victims were described in German media listings as including his wife and seven children, and the perpetrator additionally killed himself, bringing the total number of deaths associated with the event to nine (excluding himself).

Contemporary German newspaper reporting from the period (not fully available online) was cited in later compilations with headlines referencing the act as “Warum erschoß Kecinski seine Familie?” (“Why did Kecinski shoot his family?”) and noting that he had substantial financial debts (125 000 DM) at the time, which was quoted in retrospective coverage of the incident.

Because Kecinski died immediately after the shooting and there were no public court proceedings, there is no conviction record or trial testimony. Public records do not provide a detailed, verified sequence of the incident beyond what is compiled in statistical lists of rampage killers.
