Editing Henry Probus (section)

===Killers===
Following the version of Ottokar of Styria, should be sought among the Wrocław townspeople (just like Henry IV's father) two brothers, one of them was lawyer and the other doctor. The only two persons who could be identified as the brothers were John (who was an adviser of the Duchy and a lawyer) and Jakob (known as ''Magister'', so probably a doctor), sons of one Goćwina, who was a doctor in the court of Henry III the White. They still in their posts at the time of Henry IV's death. It's assumed that they acted on behalf of [[Henry V the Fat]], who wanted to obtain Kraków and with this the title of High Duke, but was not any evidence to support this. There is no other person who will take advantage of the Duke's death, and could be linked to the circumstances of the death of Henry IV.
