A 41-year-old teacher goes on trial in Germany on Tuesday accused of sado-cannibalism for sexual gratification.

The teacher identified in the German media as Stefan R under the nation's strict privacy laws, is alleged to have killed a 43-year-old technician in his apartment shortly after meeting him on a dating website.

He then allegedly cut up the victim, identified as Stefan T, and dumped the body parts at various locations across Berlin.

The prosecution plans to argue there was a "sadistic-cannibalistic sexual motivation for the crime" after the suspect allegedly ate parts of the corpse.
