Gary Michael Heidnik was the epitome of evil. FBI famed profiler John Douglas even claimed that Gary "spooked him" - he was born near Cleveland Oh in  1943 and was the last man killed in Pennsylvania by lethal injection July 6, 1999,.

In between these dates what he did was fodder for movies such as Silence of the Lambs - Buffalo Bill the character was made up of six serial killers and Gary was one of these killers. He put women into a pit, chained them to walls and shocked them with water in bizarre electrical ways to punish them; he would sit back and sneer and chuckle as they "danced" in death. 
One woman would turn the tables on him however, a woman Josefina Rivera would trick him, and what she did was horrifically beautiful - she is a true here.
What happened at 3520 N. Marshall street is just about unbelievable....except that it really happened.
