en.wikipedia.org/wiki/Ponary_massacre

The article describes the Gdańsk branch of the Polish Institute of National Remembrance (IPN) as currently investigating the Paneriai/Ponary murders. But IPN’s own list of concluded investigations states that the Ponary case ended with a discontinuation order on 30 June 2006. That means the investigation is not current.

This correction is limited to the IPN/Gdańsk part of the sentence. I am not relying on a negative inference; I am relying on IPN’s explicit publication of the case among investigations that have already been concluded.

The official Paneriai Memorial site distinguishes between two separate commemorative installations at the Polish victims’ site:

1. In autumn 1990, a wooden cross and an altar tombstone were erected.
2. In November 2000, the memorial designed by Jaroslaw Skrzypczyk was unveiled at that spot.

So the article’s wording is inaccurate because it says the Polish memorial was "erected in 1990" and then "reconstructed in 2000." According to the memorial’s own documentation, the 1990 installation was an earlier cross-and-tombstone marker, while the memorial was unveiled in 2000.

Recent reference material from the Paneriai Memorial and the online Encyclopaedia of the Holocaust by Bullets place the killings in July 1941–July 1944, not August 1944.

The Paneriai Memorial’s history page says: “From 1941 to July 1944, up to 70,000 people were executed in Paneriai.” Its page on the Jewish victims adds that “The last mass killing of the Jews in Paneriai took place on 3 July 1944.” The Encyclopaedia of the Holocaust by Bullets likewise states: “The killings took place from July 1941 to July 1944.”

So the article’s end date is one month too late. August 1944 is associated with Soviet post-liberation investigation of the site, not with the killings themselves.
