EXCLUSIVE: Dennis Rader, better known as the serial killer BTK, says prison guards tossed his cell and seized his belongings during a recent meeting with cold-case investigators.
Rader, who will spend the rest of his life behind bars, has been under investigation in Oklahoma in connection with the unsolved disappearance of Cynthia “Cyndi” Dawn Kinney, a 16-year-old cheerleader last seen leaving her aunt and uncle’s laundromat on June 23, 1976.
When Osage County Sheriff Eddie Virden visited him at the El Dorado Correctional Facility in Kansas in late April with questions about the case, he told Fox News Digital two other unexpected investigators showed up, too.
A detective from Missouri he referred to only as “Show Me” and an investigator from Kansas he dubbed “Yellow Brick Road” asked him about the disappearance of Shawna Garber, 53, on Halloween in 1990.

“They brought a lot of info I could look over, codes, maps, my old BTK logs, etc.,” he told Fox News Digital. “I did sign a Miranda with them and grant of transactional Immunity.”
However, he added, he found another surprise when he returned to his cell.

Rader told Fox News Digital that he committed only the 10 murders he confessed to after his arrest in 2005.
He had previously waived his Miranda rights and agreed to speak with Virden’s office and denied having been in Oklahoma at the time of Kinney’s disappearance.
Rader is serving consecutive life sentences in a Kansas prison for the 10 slayings between 1974 and 1991. According to the serial killer, he was inactive between the first slayings, which involved victims in two attacks in 1974, and the attacks on the third and fourth victims in 1977.

Rader’s daughter, Kerri Rawson, told Fox News Digital she does not believe either cold case fits the distinct patterns of her father’s other murders, which involved stalking his victims, keeping journals, home invasion attacks and taking “trophies.”
She said she has no knowledge of him having reason to be in Oklahoma in June 1976 and noted that Halloween in 1990 came on a weekday.
They also asked him about a break-in and entry in Topeka, Kansas, he said.
