A law enforcement team in northeast Oklahoma believes the prolific serial killer known as “BTK” may be responsible for several additional unsolved missing person and homicide cases. Now they’re hoping the public can help them identify barns and silos in Oklahoma, Kansas and Missouri that the self-proclaimed BTK killer Dennis Rader sketched in never-before-seen detailed drawings.
Last month, the Osage County Sheriff’s Office publicly confirmed it was investigating Rader as the “prime suspect” in a 1976 cold case in their jurisdiction and several other unsolved crimes across three states.
The investigators believe the killer may have buried 16-year-old Cynthia Dawn Kinney in a barn near the Kansas-Oklahoma border. Kinney was last seen at a laundromat in Pawhuska, Oklahoma, in 1976. Her body has never been found.
What? It’s only been a few months.
BTK was only arrested in 2005 and the Osage County Sheriff only got the drawings in question from Kansas police in January this year when his office opened the investigation.
There have been other investigations into cold cases around the area since he was arrested but none have turned up any links. This case is just the evidence finally making its way around to this office so they can investigate.
They also found more new evidence last month which is what has led to this announcement.
