Leo Egidius Schiffer (1956 – 21/22 July 2018) was a German serial killer, who was known as The Strangler of Aachen.
The first murder was committed in July 1983 near Alsdorf: the 18-year-old Marion Gerecht was at a bus stop when she was attacked by Schiffer.
In February 1984, Schiffer attacked 15-year-old Andrea Wernicke near the nightclub 'Rockfabrik" Uebach-Palenbeg, Geilenkirchen, country Heinsberg.
For an hour, Schiffer drove across the country with the body in the trunk until he found a place to drop it off.
However, the court relied on the repeated confession of Schiffer which also had "disclosed perpetrator's knowledge", as well as the DNA traces present at the crime scenes.
He had connected his body to the power grid using multiple cables to support autoerotic practices, and he died as a result of heart arrhythmia.
