One of three women depicted in sketches by BTK serial killer Dennis Rader showing girls bound and gagged is possibly identified

One of the three women depicted in chilling sketches by the BTK serial killer, showing girls bound and gagged with nooses, has possibly been identified.

After the eerie images were released in a bid to solve a slew of murders Dennis Rader may have been involved in, Osage County Sheriff Eddie Virden said his team has received ‘very good’ tips from the public.  

Dennis Rader, known as the BTK killer, ‘Bind, Torture, Kill’ went on a murderous two-decade killing spree during the 1970s to the 1990s, including two children in Kansas. 

He pleaded guilty to ten murders and is currently serving ten consecutive life sentences.

The images were first recovered after Rader’s arrest in February 2005, but in January, an investigation was opened into other evidence that was discovered by Wichita Police.

This included writings and sketches that officials believe may be a possible link to several unsolved cases in the area.

Virden would not disclose any further details on the possible ID of the woman in the sketch – but he did confirm the victim was the one woman pictured wearing a green dress. 

He said his team has received ‘very, very good tips’ from the public.

‘It’s going to be a busy week. We have a lot of follow-ups to do, of course, a lot of interviews to do. Barn-wise, we’ve got a lot of things sent to us for us to check out,’ Virden said, according to CNN.

The three digital images showed different female victims gagged – some had a noose around their neck with their arms and legs bound. 

Each wore a short garment and had a terrifying expression on their faces. 

Investigators believe all three victims were being held captive in a barn.

Virden previously said: ‘We know from things Dennis said on this exact photograph that it was a drawing he created from an actual barn.’ 

One of the sketches showed a young blonde female in pigtails wearing a green top, with her arms and legs bound and sitting on what looks like a stack of hay. Officials noted the black piping in the picture that may be the walls of a barn. 

A second drawing showed a young dark-haired girl in a red top sitting on her knees as she is bound and gagged with a noose looped around her neck. The image showed brown horizontal lines. 

The third sketch differs from the other two as it was drawn in black ink and drawn in a different angle. The victim was seen lying flat and bound by her neck to a staircase post that appeared to be in some type of barn loft space.

Last month, police raided the ex-Air Force sergeant’s former property in Park City, Kansas, over the disappearance of Cynthia ‘Cyndi’ Dawn Kinney, the 16-year-old cheerleader who was last seen in 1976. 

Detectives said they hope the probe will help to tie him to more grisly unsolved cases. Osage County Undersheriff Gary Upton said his department is ‘continuing to follow leads in unsolved missing persons and murder cases possibly related to BTK.’

Rader’s adult daughter, Kerri Rawson, has been assisting police in trying to help investigators crack the case of the other unsolved crimes.

She told DailyMail.com on Monday that the new drawings that came out this weekend have been ‘evidenced and private to only law enforcement until this weekend.’

‘Osage County Sheriff’s Department were trying to find out were these actually women that were victims and murdered or what my dad fantasized about,’ she said.  

She explained those drawings were released because they had certain details about barns that investigators are looking into.

The sketch of the young woman in the green top may be connected to a 1991 missing person from the Southeast  Kansas area.

 ‘We have an ID and a pretty strong lead on her, but we don’t have a location so they are trying to find a location,’ Rawson said.

Rawson said the black-and-white sketch that she refers to as ‘barn girl number one’ and the drawing of the young woman in the red top continues to be a mystery.

The victim could be any missing person in the Kansas, Missouri, Oklahoma or Arkansas areas between 1963 to the time of her father’s 2005 arrest. 

‘We have no idea right now on a timeline or missing person information on them that is why we released them on a missing person’s poster yesterday with a partner,’ she said.  ‘Those are my theories.’

Since the images release to the public, she said, some of her colleagues have been using AI to try and enhance the drawings which, she said, have been helpful.

Rawson revealed to DailyMail.com that of the 200 sketches that her father drew only ten of them had color.

‘We released these because it is rare that my dad would use color,’ she said. ‘The black and white sketch has very specific details. Someone might recognize it.’

Rawson said her father had taken some drafting classes at college and as a youngster remembered seeing his drafting materials out, a drafting board, ruler and some drafting tools.

‘I only ever saw him draft sketches of the garden or a second addition that we were going to put on the house but, then he got laid off, and we never did it.’

She recalled that her fathers liked to using his drafting skills to draw barns and silos and said he ‘was very particular when he drew those.’

But, doesn’t remember ever seeing him draw people or use color or colored markers. 

The images released over the weekend may have been a ‘secret hobby’ something he may have done privately, when he was on the road.

‘We believe he kidnapped these people. Took took them someplace to draw them in real time, in between binding them, somewhat torturing them, and maybe drawing them after they were killed.’

She added: ‘So we think these are done in real time, but we’ve got to solve that and figure that out. That’s what we’re trying to solve right now is, ‘How many are there? Who are they? Where are they from? Where cam we find them? We could be at this a very long time,’ she said, in part. ‘That’s my working theory.’

Rawson said at first look the drawings appear sketched in the ‘first person,’ and described them as ‘very particular.’ 

‘There are some that have extreme detail, like the first black and white one at the barn. There’s a detail down to her mascara, that’s smudged, the exact bondages, and what the barn looks like.’
