Findings thumb|upright=1.35|Jedwabne memorial, 2011 On 9 July 2002 the IPN issued a press release on the findings of its two-year investigation, signed by the chief prosecutor, Radosław J. Ignatiew. The IPN found that at least 340 Jews had been killed in the pogrom, in two groups. The first group consisted of 40 to 50 men, who were murdered before the barn was set on fire. The second group consisted of about 300 people of "both sexes of various ages, including children and infants". The second group was "led into a wooden, thatched barn owned by Bronisław Śleszyński. After the building had been closed, it was doused, probably with kerosene from the former Soviet warehouse." The exact number of victims could not be determined. The previously estimated figure of 1,600 "seems highly unlikely, and was not confirmed in the course of the investigation".
