October 18, 1927 - Zdzisław Marchwicki
His case stands out not only for the crimes attributed to him but for the unresolved questions surrounding his conviction — a reminder that the machinery of justice, under political pressure, can produce verdicts that later generations struggle to trust. Operating across Poland during the 1960s, Marchwicki and alleged accomplices were linked to a series of killings that spanned six years before authorities closed the case with executions.
From Wikipedia
Zdzisław Marchwicki (18 October 1927 – 26 April 1977), known as The Zagłębie Vampire (Polish: Wampir z Zagłębia), was an alleged Polish serial killer who, together with several accomplices, was convicted of killing 14 women and attacking 7 others around the country from 1964 to 1970. For this, Marchwicki was executed in 1977, but since then his guilt has been questioned.
