I mentioned the BTK case on this board before when a psychic from England and camera crew went to Wichita to get a feel for the case.
The BTK (bind, torture, kill) killer has been connected to 8 murders between 1974 and 1986. He resurfaced in March of 2004 and began communicating with various news agencies and law enforcement agencies.
A website with some history about this killer is at BTK
Here is a link to a news site with some new developments in the case.
I hope they have him.
