When Duke Theodo and his son Lantpert learned of Uta's pregnancy, Lantpert went after the bishop. Lantpert caught up with Emmeram in Helfendorf (now part of the Munich suburb of Aying) on the old Roman road between Salzburg and Augsburg on the Via Julia Augusta and greeted him as "bishop and brother-in-law". According to popular tradition, wanting to protect the real culprit, Emmeram did not defend himself, and received numerous wounds. Lantpert and his followers tied Emmeram to a ladder and proceeded to torture and cut him into pieces.
