When Sweyn returned to England and attempted to secure a pardon from the king, Beorn and Harold refused to return any land. With three others, Beorn was guided to Bosham by Sweyn, where he was taken captive. He was sent by ship to Dartmouth, killed and his body buried.
Harold, Sweyn Godwinson's brother, later had Beorn reburied adjacent to his uncle King Cnut, in the Old Minster, Winchester.
Beorn may have had a son. Morkinskinna recounts an Åsmund, nephew of king Sweyn Estrithson of Denmark, explicitly describing him as son of the king's brother Beorn, yet Harald Hardrådes saga, part of Heimskringla, calls the same Åsmund the sister's son of Sweyn.
