BTK claims he's innocent in Cyndi Kinney case as 'police have complete lack of solid evidence'

Serial killer BTK claims he's innocent in 1976 Oklahoma cold case disappearance of 16-year-old Cyndi Kinney, as police have a 'complete lack of solid evidence', and she vanished a decade before he visited Oklahoma. 

BTK, whose legal name is Dennis Rader, is known for 'binding, torturing, and killing' his 10 victims in Wichita, Kansas, from 1974 to 1991. 

Kinney, a 16-year-old cheerleader, went missing on June 23, 1976. Authorities questioned if Rader, who had killed five people by that time, was involved, but they never released why they thought the murderer was involved. 

Rader, who confessed to killing 10, has denied any involvement in Kinney's case and told Fox News the 'sheriff has what I call complete lack of solid evidence' and that the young girl disappeared before he came to Oklahoma. 

Investigators who questioned Rader, who waived his Miranda Rights, said he disputed several claims they threw at him and claimed to have an alibi to prove it.

Rader, who worked at ADT - a security services company - at the time, said that ADT had no involvement in the area that Kinney worked.

'Bank prewire [was] being installed close by, but no work by ADT in Oklahoma from the Wichita Office,' he told Fox News. 

In addition, he said he didn't start working in Oklahoma until the 1980s, where he helped with Boy Scout camping trips and worked for the Census Bureau in the 1990s. 

'Give me a break,' he said. 'I drove down there on a whim to Osage County, from Wichita, when I'd never been there before. I helped on 1990 Census in Oklahoma, but the timeframe doesn't match anything I did.' 

His daughter, Kerri Rawson, also doesn't believe Kinney's disappearance matches her father's typical style - stalking, keeping trophies, and home invasion attacks. 

'While it is my hope and prayer this missing person cold case gets solved for the family and friends of Kinney, in no way do I believe my father is connected,' she told Fox News. 'And, in fact, I believe he’s telling the truth on this, as he has done since 2005 on the 10 he did commit.' 

She also doesn't believe her father had any reason to be in Oklahoma in 1976. 

Osage County Sheriff Eddie Virden said the investigation is too early to give specifics but said they 'won't leave anything uninvestigated.' 

He claimed Kinney (pictured) disappeared a decade before he went to Oklahoma, where he worked with the Boy Scouts in the 1980s and the Census Bureau in the 1990s 

'I can't tell you whether we're going to come up with anything or whether we’re not,' he told Fox News. 'We hope we come up with something for closure and justice for victims. But an investigation is an investigation; sometimes they go places. There may be some things that we felt like we need to look into, and we're following up on those.' 

Rader murdered 10 people, including two children, in Wichita, Kansas over a 17-year stretch. He was arrested in 2005 and is currently serving 10 consecutive life sentences at a Kansas prison.

He claimed there was a 'demon' inside of him that 'entered me when I was young' and 'basically controlled me,' he claimed in a 2018 documentary. 

When asked if he had any feelings for his 10 victims, Rader replied: 'Yes, I do'.

'I mean, I have a lot of feelings for them,' he said. 'I guess it's more of an achievement for this object in the hunt. Or sort of more of a high, I guess.'

Rader, who was a former church leader and hid his killings from his wife and two children, also revealed in the interview that he started noticing his dark side back in the eighth grade.

He has previously said that lust and a desire for fame and power drove him to murder.

Rader evaded authorities for three decades but continuously taunted police about the killings, which eventually led to his downfall.

He started communicating with Wichita police detectives via a floppy disk that authorities ended up tracing back to his church.

Rader killed Joseph Otero, Julie Otero, Joseph Otero ll, and Josephine Otero on January 15,1974. He killed Kathryn Bright on April 4, 1974; Shirley Vian on March 17, 1977; Nancy Fox on December 8, 1977; Marine Hedge on April 27, 1985; Vicki Wegerle on September 16, 1987; and Dolores Davis on January 18, 1991. 

Rader recently said he sympathizes with Idaho murders suspect Brian Kohberger. 

Kohberger, 28, studied under the same psychologist who wrote the book on Rader, Dr. Katherine Ramsland.

The murderer said that he sympathizes with Kohberger, who has been in solitary confinement awaiting his trial.

His daughter, Kerri Rawson, told Fox News.com that her father said: 'Since I spent from Feb. 2005 to April 2005 in a cell by myself, I know how he feels – very lonely.'

Rader added that he spent time with his defense attorney and found ways to pass the time and wanted to go through 'everything' prosecutors had on him – despite confessing on the day of his arrest.

Rawson revealed that her dad was 'going back and forth' between whether he should plead guilty or not, adding: 'One difference is dad confessed and seemed relieved while Kohberger has to feel very alone.'

She added that she has seen 'fan mail' sent to Kohberger which is very similar to that which was sent to her father – explaining that women 'are in love' with them.

BTK's daughter previously said that Kohberger could have been in contact with her father after discovering that he had been taught by Dr. Katherine Ramsland while at DeSales University.

It is something that he has since denied, with the pair having a 'close relationship' while writing the 'Mind of a Murderer' book.
