9 Serial Killers Who Are Now Free

Wolfgang Abel and Marco Furlan were a pair of neo-Nazis who carried out a system of politically-motivated attacks throughout the pair's homeplaces of Italy and Germany, as well as the Netherlands. They were both scions of upper class families living in the region of Verona, Italy.

Abel and Furlan became fast friends in high school, united by the idea that they were destined to be the heroes to remove deviants from the world. Said deviants were anyone they didn't like: prostitutes, homosexuals, drug addicts, 'sinful' clergymen, and anyone involved in pornography.

Adopting the name 'Ludwig' the pair had a terrifying modus operandi involving burning people alive with molotov cocktails before fleeing the scene. Their first victim in 1977 was a man who they believed was guilty of being both a drug addict and a 'gypsy', due to his Roma heritage.

By the time of their capture seven years later they had a total of 28 victims to their name and had been caught because of up-to-code fire safety products in a cinema they tried to set on fire. The patrons beat them into submission until they were rescued by police, just before they could be lynched. Ultimately they would spawn copycat attacks through the years while in prison, and continued to claim their own innocence. By 2010 both men were out on probation and by 2016 they were entirely free.
