(Had to do a little research on this one, but, it's been a slow day

Oddly enough, the people in Latvia continue to honor the Nazis who freed them from the Jewish communists,
Latvia Still Honors the Biggest Jew-Killing Machine in World History
Here's what they said in 1941 ...
"On July 2, 1941, the first number of the bilingual newspaper Kurzemes Vāds (The Word of Kurzeme) could proclaim, speaking of Liepāja:
“Our native city has been freed from the yoke of the Jews and the Bolsheviks. We thank therefore our führer Adolf Hitler. His fight is our fight.”
Here is why the Communists/Jews were hated in Latvia
Latvia Year Of Horror
As soon as the Germans liberated Latvia they formed Latvian auxiliary police units that were ready to revenge the Latvians ...
Latvian Auxiliary Police
"Owing to the initiative of the EK (Einsatzkommando), the auxiliary police force consisted of 240 men and had been strictly organized. New men were currently being enlisted. They helped the EK as auxiliary police and were on duty in the 6 police districts established so far. Some members had been assigned to Kriminalpolizei and Sicherheitspolizei work. By July 7 the Latvians arrested 1125 Jews, 32 political prisoners, 85 Russian workers, and 2 women criminals, the greater part during the last days. This is due to the EK backing the Latvians. Actions against the Jews were going on in an ever-increasing number. Conforming to a suggestion of the EK, the Jews were being evacuated by the auxiliary police force from all houses still standing. The apartments were being allocated to non-Jewish inhabitants. The food supply was inadequate as nearly all stocks were destroyed by fire. The arrested Jewish men were shot without ceremony and interred in previously prepared mass graves. 400 Jews were killed during pogroms in Riga, since the arrival of EK 2; 300 by the Latvian auxiliary police. By 1944, the occupation power, with the collaboration of the Self-Administration, had formed a total of 33 auxiliary police battalions
Thus, there apparently were some local 'mass' killings of Jews in Latvia and Lithuania, motivated by locals to revenge the predations of the Jewish communists who supported the Soviet occupation.
So, the relevant questions are what is the provenance of the vid allegedly of Liepaja above, and where are the mass graves, and what has been determined about the identity of the victims?
