On 30 June 2003 prosecutor Radosław J. Ignatiew announced that the investigation of "the mass murder of at least 340 Polish citizens of Jewish nationality in Jedwabne on July 10, 1941" had discovered no living suspected perpetrators in the Jedwabne atrocity who had not already been brought to justice, and so the IPN investigation was now closed.
2003年6月30日，检察官拉多斯瓦夫·伊格纳蒂耶夫宣布，截至当时针对“1941年7月10日耶德瓦布内的至少340名波兰籍犹太公民被大规模杀害”进行的调查中，并未发现仍然在世但从未被绳之以法的耶德瓦布内暴行嫌犯，因此IPN调查现已结束。
