 It is nevertheless undisputed that Frederick was murdered during his journey home by Count Henry VII of Waldeck and his henchmen, who included Friedrich von Hertingshausen and Konrad von Falkenberg.The murder may have served to get rid of a royal candidate; or the story of the royal election may have sprung up to find a motive for the murder.The assassination caused much concern at the time; a stone cross ("Kaiserkreuz") was erected at its location in Kleinenglis near Fritzlar.
