Kalonymus Kalman Shapira was a Polish rabbi who died in the Trawniki concentration camp. At the end of the war, the Nazis decided to execute all the remaining prisoners of the concentration camps in operation in operation "Harvest Festival". Mr Shapira was shot.
The manner of death is an execution. However, I can not make myself add this as a statement of fact for Mr Shapira. The reason for this is that execution is considered a synonym of "capital punishment". Capital punishment has as its narrative: "legal process whereby a person is put to death by the state as a punishment for a crime". The Neurenberg trials have concluded that what happened may have been expedient but it was absolutely not legal.
The number of notable people who died in a Nazi concentration camp seems to be low. Only 586 people among many false positives.
