The Murders of Piotr and Alicja Jaroszewicz
Former Polish prime minister Piotr Jaroszewicz and his wife, Alicja Solska-Jaroszewicz, were killed in their home in Warsaw's Anin district during the night of August 31 to September 1, 1992. Decades of investigation have produced repeated prosecutions but no final conviction. In November 2024, three men were acquitted of the central charges; prosecutors filed an appeal in September 2025.
Piotr Jaroszewicz, who served as prime minister of the Polish People's Republic from 1970 to 1980, and his wife Alicja Solska-Jaroszewicz were murdered in their Warsaw-Anin home in 1992. The case became one of Poland's most persistent post-communist-era murder mysteries.
The 1992 murders
The killings occurred during the night of August 31 to September 1, 1992. Investigators developed competing theories over the years, including robbery-related explanations. This page does not present any theory as established fact unless supported by a court finding.
A new prosecution decades later
Years after earlier investigative failures, prosecutors brought a new case against Robert S., Dariusz S. and Marcin B.. The prosecution alleged that the men were involved in a robbery at the Jaroszewicz home and in the killings. Robert S. faced the central murder allegations, while the other defendants were accused of participation-related offenses.
Those claims remained allegations throughout the trial. The defendants were entitled to the presumption of innocence.
November 2024 acquittals
On November 22, 2024, the Warsaw Regional Court acquitted all three defendants of the most serious charges in the Jaroszewicz case. The court pointed to inconsistencies and problems in the evidentiary record and pre-trial investigation.
The acquittals were not the same as a finding that the murders had been solved in some other way. They left the identity of the killers unresolved.
Prosecution appeal
After the written reasons for the 2024 judgment were completed in August 2025, prosecutors reviewed the court's reasoning. On September 1, 2025, the Kraków Regional Prosecutor's Office filed an appeal seeking to have the acquittals overturned.
The prosecution argued that serious procedural errors affected the first-instance judgment. That is the prosecution's appellate position; it is not a final judicial finding.
Status reviewed in August 2026
For this page's August 29, 2026 review, current Polish reporting continued to describe the prosecution appeal and the unresolved nature of the case. No later final appellate judgment resolving the Jaroszewicz murders was located in the sources reviewed.
The archive therefore classifies the case as Unsolved / Appeal pending after acquittals.
