Analysis of information sources in references of the Wikipedia article "Herberts Cukurs" in English language version.
Cukurs had been a notoriously cruel SS officer, who supervised massacres at the Riga concentration camp from horseback.
Herberts Cukurs joined in the rampage, mercilessly beating and shooting as they pleased. Those unfortunates who could not rouse themselves or moved too slowly, Arajs, Cukurs, and their followers shot. Those that resisted or refused to go were also shot on the spot. Blood literally flowed in the streets.
One of the leaders of the Arajs Commando was Herberts Cukurs, who many remembered as being horrifically brutal, beating, and shooting those Jews who could not keep up with the march for an unknown destination. Isaak Kram, a Jewish engineering student, recalled how he had got close to the former pilot: An old Jewish woman screamed because her daughter was not allowed to climb with her on to the truck. Cukurs pulled out his gun and shot the old woman. I was an eyewitness to the shooting. I also saw with my own eyes how Cukurs aimed his gun at a baby who was crying because he could not find his mother. Cukurs killed that baby with a gunshot. Kram was not the only witness to Cukurs committing infanticide. Another was the twenty-year-old David Fiszkin.
Rafael Shub, for example, noted that on July 2, 1941, Cukurs burned to death eight Jews in the new Jewish cemetery: the synagogue sexton Feldheim, his wife and four children, and Cantor Mintz and his wife. Abraham Shapiro, a survivor who had been incarcerated at the headquarters of the Arajs Kommando at 19 Valdamaras Street after Cukurs had taken over his family's apartment, related that the deputy commander [Cukurs] had personally murdered two Jews, one of whom was named Leitmann, who failed to appear at a lineup as ordered. He also witnessed Cukurs and his fellow Latvian officers sexually molest and torture a young Jewish girl while he played piano at a command performance ordered by Cukurs in the apartment he had seized from the Shapiro family. The most damning evidence was supplied by Max Tukacier, who on September 23, 1948, testified that he was among a group of Jews arrested by the Arajs Kommando and taken to their headquarters, where he witnessed how numerous Jews were tortured and subsequently shot on Cukurs's orders. On July 15, 1941, he personally saw Cukurs order an elderly bearded Jew to rape a 20-year-old Jewess in front of a crowd of Latvian police and prisoners, and when he proved incapable of doing so, forced the man to kiss the naked girl all over her body again and again. Those prisoners who could not bear to watch this ugly sight—some 10 to 15 of them, including several women—were beaten to death by Cukurs with the butt of his pistol. Tukacier also testified to Cukurs's active role in the mass murders of November 30 and December 8, 1941, noting that he beat and shot men, women, and children who could not keep pace on the death march to Rumbula.
