I was just watching a documentary on serial killer Gary Ridgeway >>> http://en.wikipedia.org/wiki/Gary_Ridgway <<< and his story is so bizarre IMO. Here is a guy who is 151 lbs and from 1982 to 1998, that's 16 years, he picked up and murdered at least 49 street walking prostitutes and as many as 71 or more and this went on for 16+ years till he was finally captured.
He is known as the Green River Killer. This all took place in the Seattle Washington area. He drove an old blue pick up truck and each of the girls he would strangle. I pondered, how the hell can a 151 lb man succeed in strangling sooo many women, either in the woods or at his home. I mean, it's not like he was 190 to 230 lbs, a big giant strong man, but then if you look at the Wikipedia article, you will notice most all of his victims were between the ages 16 and 22. So these truly were young girls. They were all prostitutes, hitch hikers or ladies who were walking the streets.
This baffled the police for 16+ years, until he was finally caught via more advanced DNA technology.
In this day and age of all kinds of kinky perversions and varied sexual interests, that are basically harmless, but mutually enjoyed via consenting adults, it amazes me how a guy like Gary Ridgeway was not only able to do what he did, but to do it for 16+ years, driving an old blue pick up truck and living in the same old house and never being caught till 16 years later.
