Freikorps Oberland

An infamous individual who would pop up as a potential suspect was Adolf Gump, a Bavarian citizen who hailed from the municipality of Karlskron, about 20 kilometers north of Weidhofen.

Gump became involved in a far-right paramilitary organization called the Freikorps Oberland and was suspected of being involved in the murders of nine farmers in the Upper Silesia region of Poland during a series of uprisings which occurred during that time period.

On April 9th, 1922, just nine days after the Hinterkaifeck murders took place, a warrant was issued for Gump's arrest for his role in the Upper Silesia murders, but it does not sound like he was ever brought to justice for this, and he died in Würzburg in February of 1944 at the age of 54.

Well, eight years later, in 1952, Adolf's brother, Anton Gump, was arrested by the Munich police.
