Quite shocking really, although this did instantly make me think of a recent series on the Discovery Channel there were two episodes of "Crimes That Shook the World" that had some striking similarities to this case, although most serial killers you could say fall into this pattern. They were all prostitutes, they were found in a rural area pretty much like a 'stomping' ground for the killer, one was strangled (not heard about the rest but it is quite usual for serial killers to kill in the same way). Coincidence that these killlings have just recently started only a month or so after this series, it was quite detailed in the shortcomings of the police in foreign countries, things they missed, how the killer managed to get away with certain things, how he identified and lured his victims away from their normal 'patches' or neighbourhoods? Did these programs prove the trigger for this person to start on his path of rape/killing?
The Vienna Strangler - Jack Unterweger - In 1990, the first year after his release for killing an 18yr old prostitute by strangling her with her bra (in 1974), law enforcement in Austria found later that he killed six prostitutes mostly by strangling them with their bra's. In 1991, he was hired by an Austrian magazine to write about crime in Los Angeles, California, writing articles about prostitution and riding around town with the local police. During his time in Los Angeles, three prostitutes Shannon Exley, Irene Rodriguez, and Sherri Ann Long were beaten, sexually assaulted with tree branches, and finally strangled with their own brassieres. He was convicted and sentenced to life in prison but appealed, whilst waiting for the appeal he took his own life, so the sentence was never legally valid. The damning factor was that he used the exact same 'signature' knot on his hangmans noose as used in all the previous murders.
The Phoenix Strangler - Sipho Agmatir Thwala - South Africa's "Phoenix Strangler," Sipho Agmatir Thwala, is suspected of raping and strangling 19 victims with their underwear before burying them in shallow graves. On March 31, 1999, the Durban High Court found Thwala guilty of only 16 murders and 10 rapes, and he was sentenced to 506 years in prison.
