Editing Fritz Haarmann (section)

===Hans Keimes===
Haarmann is also strongly suspected of the murder of Hans Keimes, a 17-year-old Hanover youth who was reported missing on 17 March 1922<ref name="Monsters of Weimar p. 101"/> and whose nude, [[binding (knot)|bound]] body was found in a canal on 6 May. The cause of death was listed as strangulation, and the body bore no signs of mutilation. A distinctive handkerchief bearing Grans' name was found lodged in Keimes's throat.<ref name="Monsters of Weimar p. 101"/>

Prior to the discovery of Keimes's body, Haarmann is known to have both visited the youth's parents offering to locate their son and to have immediately thereafter informed police that he believed Grans was responsible for Keimes's disappearance. However, Hans Grans is known to have been in custody at the time of the disappearance of Keimes.<ref name="ReferenceE"/>

Two weeks before the disappearance of Keimes, Haarmann had returned to his Neue Straße apartment, having served six months in a labour camp for several acts of theft he committed in August 1921. Upon his return, Haarmann discovered that Grans had stolen much of his personal property and fraudulently obtained and spent his military pension while he had been incarcerated. This resulted in a violent argument between the two men culminating in Haarmann evicting Grans. Shortly thereafter, Grans and a criminal acquaintance named Hugo Wittkowski returned and further ransacked the apartment. Haarmann likely murdered Keimes in an attempt to [[Frameup|frame]] Grans in reprisal for the theft of his property and pension.<ref name="ReferenceH"/>

Haarmann was not tried for the murder of either Koch or Keimes. Officially, both cases remain unsolved.<ref name="Monsters of Weimar p. 101"/>
