Roman Yossel Remis was the forerunner during the Yom Kippur celebration at the Halle Synagogue. He, like the other people there, witnessed up close, as the assassin Stephan B. tried to penetrate into the building. How he shot a passer-by out in the street. In his video, which he recorded the evening after the attack, he describes the minutes of fear and uncertainty. His descriptions coincide with our research into the course of the attack.
