Investigators told German media that the man then rampaged though nearby streets, armed with the shotgun and a pistol, before being gunned down by armed cops.
GERMAN league star Kenneth Schmidt has been left in shock... after armed police shot his stepfather DEAD in the street.
Schmidt bravely turned up to Hannover training on Tuesday despite learning of the tragic drama the day before.
Reports say the man, named as Christoph S., threatened the pair at their home in the quiet village Eichstetten near Freiburg.
A Hannover spokesman said: "We ask for people's understanding that we are unable to comment more precisely about this matter at this time.".
