BTK killer says prison cell searched during cold-case questioning

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.

The Kansas woman was raped, strangled and found dead a month later in Missouri, but authorities could not identify her remains until 2021 through DNA testing.

Rader denied involvement in both cold cases, and while he said he was "done" speaking with Virden, he said he "enjoyed" meeting with the investigators on Garber's case.

"They brought a lot of info I could look over, codes, maps, my old BTK logs, etc.," he noted. "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. "Everything that I had wrote on or kept was gone," he said. "Later that day, one box returned with no reason why."

Virden previously said he could not discuss specifics in the case and said the investigation would be thorough and fair while calling it premature to talk about charges or an arrest.

"I can't tell you whether we're going to come up with anything or whether we’re not," he said. "We won't leave anything uninvestigated."

Rader said 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.

She vanished 10 years before he began leading Boy Scouts on camping trips in the region in the 1980s, he said, and he didn't go there to work for the U.S. Census until 1990.
