Czesław Konieczny was a Polish farmer who killed his mother and six siblings in their sleep in Pieruszyce, Poland during the night from December 1 to December 2, 1929.[1][2][3][4][5]

Killed them, because they opposed marriage. Was arrested, admitted the murders, showed no remorse. Threw axe down a well after murders. His oldest sister had one arm severed, the others skulls crushed, throats cut. Brother Stanisław awoke, tried to escape, was caught and mortally wounded died in hospital. He then escaped, but was arrested soon thereafter. Was held in prison in Pleszew, transferred to prison in Ostrow on December 5.[6][7]

He was sentenced to death once for every murder on May 28,[8] and executed by hanging at the prison in Ostrów on July 19, 1930.[9]
