JonBenét Ramsey's 'killer' Gary Oliva scowls as he's pictured out for first time since being freed from prison: Convicted pedophile confessed to 'accidentally murdering' child pageant princess but was never charged

JonBenét Ramsey's 'killer' Gary Oliva has been pictured out for the first time since he was released from prison where he served time for child pornography charges. 

Oliva, 60, confessed to killing the six-year-old beauty pageant star 'by accident' in letters exclusively obtained by DailyMail.com. 

The 60-year-old is a convicted pedophile who was previously serving a 10-year-sentence in a Colorado prison for child pornography, but was let out two years early and has been roaming freely since January 31. He has not been charged with the child's murder, despite his repeated confessions.

He was pictured on February 28 outside of the halfway house where he is currently residing in Denver, Colorado.

Wearing an all black outfit with his hood up, Oliva was seen standing with his hands in his pockets as he scowled and surveyed his surroundings in pictures first published by The U.S. Sun.

At the time of Ramsey's murder, Oliva frequently hung out at St Thomas Aquinas Catholic Center just 13 houses away from the Ramsey family

Oliva was caught in 2016 after he uploaded images depicting children being abused to his personal Gmail account on public Wi-Fi connections all over Boulder, Colorado.

He was found to be in possession of 695 images depicting child pornography on his phone.

The pedophile also had 335 photos of and relating to JonBenét.

The young pageant queen was found dead on December 26, 1996, after she was reported missing from her home in Boulder, Colorado.

Her parents, Patsy and John, had woken up early to get ready for a trip, when the mother discovered a ransom note on the stairs demanding $118,000 for their daughter’s safe return. 

Despite the note's warning to not involve the authorities, Patsy immediately called the police and they arrived at the home at 5:55 am.

JonBenét was found dead in the basement of the home with an autopsy later revealing that her cause of death was strangulation.

Oliva was a longtime suspect in the murder case, and in letters sent to a high school classmate he admitted that he had killed JonBenét, but said it was an 'accident' and that she 'slipped.'

The pedophile wrote in the letters: 'JonBenét completely changed me and removed all evil from me. Just one look at her beautiful face, her glowing beautiful skin, and her divine God-body, I realized I was wrong to kill other kids. Yet by accident she died and it was my fault'

The pedophile, who was once jailed for trying to strangle his mother, wrote: 'I never loved anyone like I did JonBenét and yet I let her slip and her head bashed in half and I watched her die. It was an accident. Please believe me. She was not like the other kids.' 

In another letter, Oliva wrote, 'JonBenét completely changed me and removed all evil from me. Just one look at her beautiful face, her glowing beautiful skin, and her divine God-body, I realized I was wrong to kill other kids. Yet by accident she died and it was my fault.'

The letters were sent to music publicist Michael Vail, a former high school classmate of Oliva's.

In an interview with Dr. Oz, Vail was asked: 'Are you concerned at all that because of a deeper mental illness or had she had another mental illness, Gary's obsessed with JonBenét could be confab leading all this making it up?'

Guest commentator Nancy Grace interrupted, asking bluntly: 'Did he say he wanted to eat JonBenét?'

'Yeah,' responded Vail.

That managed to stun Dr. Oz, who looked at his guest and said: 'I'm sorry, say that again.'

Vail, who seems to be in disbelief himself, explained: 'Yeah. I know it's some pretty heavy duty stuff, he's just talking about cannibalism.'

The old classmate of Oliva then revealed other disturbing statements that he had overheard his friend say.

'Gary would break into the University of Boulder Colorado. There was a skeleton in there and he wanted to taste what human bones would taste like,' says Vail.

'So he tried biting the skeleton and he told me how disappointed it was that was covered with shellac, and he couldn't taste the bone.'

Oliva, who admitted his obsession with JonBenét, was homeless and sleeping on the streets of Boulder at the time of her killing.

He frequently visited the University of Colorado campus and hung in and around the St. Thomas Aquinas Catholic Center, where he collected his mail and hung out with other homeless people in the parking lot, according to the US Sun.

The University of Colorado campus is less than a mile away from JonBenét's home - and the church is just 13 houses away. 

There was a long alleyway running behind the properties that connected the church to the Ramsey's house, meaning that someone could move between the two locations easily and potentially undetected.

JonBenét's window was also visible from the alleyway.  

Despite Oliva's confessions and his history of child sex abuse, there are other suspects in the unsolved case. 

Patsy Ramsey had been a longtime suspect in the death of her daughter, with conspiracists speculating that she lost her temper with the little girl and killed her, only to then try and cover it up with a fake ransom note.

Both Patsy and John were formally exonerated in 2008 thanks to developments in DNA technology, though many suspect that the mother still played a hand in her daughter's death.

Patsy, who died in 2006, had her handwriting analyzed by experts to see whether it matched the writing on the ransom note.

John confirmed in December that a new handwriting analysis proves his wife's innocence and further points to convicted pedophile Gary Oliva as the real perpetrator who killed his six-year-old pageant queen daughter.

The analysis focused on slant variations, pressure points, spacing, letter sizing, and further characteristics present in both documents.

Both experts agreed on consistent similarities, for instance the present in lowercase A's found in both Oliva's writing and the killer's.

McCarty highlighted a pattern of flattened tops in the letter A over the traditionally more curved method as well as an overall similar shape

Two handwriting experts, Mozelle Martin and Dawn McCarty, conducted independent analyses obtained by The U.S. Sun, finding significant similarities between Oliva's writing and the ransom note of the killer.

The bombshell report revealed a score of 1.75 on a scale of 1 to 5 - with 1 being a definitive, identical match to the ransom note.

McCarty told The U.S. Sun, 'You can't make this up.... two separate sets of documents by two different authors that have the exact same spacing and all the consistent inconsistencies, how could that possibly be?'

Another suspect in the murder of JonBenét was John Mark Karr, 58, who claimed 17 years ago that he was with JonBenét when she died.

He said her death was an 'accident' and that he had loved her and was 'very sorry for what happened to JonBenét.' 

John Mark Karr, then 42, was extradited from Thailand and arrested for the 1996 murder of six-year-old JonBenét Ramsey

Karr was eventually released, over the objections of some FBI agents, when his DNA could not be matched to anything at the crime scene. Authorities said he knew details about the case that had not been released to the public 

In 2006, authorities extradited Karr from Thailand but were ultimately unable to link him to the scene of the crime and so felt compelled to release him.

In an interview with The Messenger, Karr said: 'I am not crazy. I am not delusional.'

'There's so much more to my story,' he said, adding that he has 'been investigated by the FBI for many more crimes' and is living outside the US 'for my own safety.'

Though most ultimately dismissed Karr's claims about being at the scene as elaborate lies, not everyone thought the tale was meritless.

'Everyone was so quick to say that I was a liar or delusional,' he said. 'Did it ever occur to someone that I might have been trying to protect someone else?'

He declined to elaborate, but one possible explanation that some police were open to at the time is that Ramsey's killer did not work alone.

When asked if he was with JonBenét when she died, or if he had killed her, Karr shut up and said he did not want to incriminate himself as the case continues to be investigated nearly 27 years after the crime.
