(HorizonPost.com) – Investigators last week searched a Kansas residential property formerly belonging to BTK serial killer Dennis Rader in connection to the disappearance of an Oklahoma teenager in 1976, CNN reported.
In a press release last week, the Osage County Sheriff’s Office in Oklahoma said investigators are also looking into whether Rader can be linked to other unsolved murders or missing persons in Kansas and Missouri.
Rader, who in 2005 pleaded guilty to murdering ten people in Kansas over the course of nearly 20 years, is serving multiple life prison sentences. In a letter found long before his capture, Rader named himself “BTK,” which is short for “bind, torture, kill.”
Osage County Sheriff’s investigators conducted a 3-day search of Rader’s former Park City, Kansas property alongside the Park City police department, according to the press release.
Gary Upton, Osage County Undersheriff, said last Thursday that the search turned up materials of interest, including what he described as “trophies” belonging to one female.
The house was bulldozed in 2006. The evidence was discovered in a hole hidden under concrete that was removed by crews during the search, according to Undersheriff Upton.
The hole was reinforced with roofing shingles and the ground was covered with concrete pavers.
Upton said the search team found chains believed to be used for bondage, as well as C-clips used to secure a person’s feet or legs.
According to the press release, last week’s search for “items of evidentiary value” was prompted by “specific leads” received by the Osage County Sheriff’s Office.
The sheriff’s office is seeking evidence connected to the disappearance of Cynthia Dawn Kinney who was last seen in 1976 at the age of 16. According to the sheriff’s office, Rader is a suspect in Kinney’s disappearance as well as other unsolved cases from the area.
