Murders at Hinterkaifeck

Investigators placed the killings between about 7 and 10 p.m. Four victims were found in the barn and Josef and Maria inside the residence. The often-repeated claim that each barn victim was deliberately lured there is a reconstruction, not an established fact.

  1. Andreas, the elder Cäzilia, Viktoria, and young Cäzilia are attacked in or near the barn.
  2. Cäzilia (child) is killed in the barn; later evidence suggests she lived for hours after the assault.
  3. Perpetrator kills Josef in his bassinet and Maria in her chamber using the same weapon.
  4. Later observations—among them tended animals and signs of household use—suggest activity at the farm after the killings; its duration and perpetrator are uncertain.

Cäzilia Gruber

Victim1849-1922

Wife of Andreas Gruber; found deceased in the barn alongside other family members.

SuspectDied 1914
