An investigation by ZDF, a German broadcaster, found that the phrases “Michael Stürzenberger stabbed” and “Michael Stürzenberger attack” were used in internet searches in Russia before the attack took place, raising concerns that Moscow had prior knowledge the stabbing would occur.
ZDF found further evidence of Russian internet users trying to access a webcam feed of Mannheim’s town square, the scene of the attack, shortly before it occurred. This would have allowed them to watch it unfold in real time.
