Obsessed JonBenét Blogger Arrested For Allegedly Sexually Assaulting A Child David J. Hughes implied in his book six-year-old Ramsey enjoyed the attack.

In a spectacular new twist in the JonBenét Ramsey case, a sicko obsessed with the slain pageant princess has been busted for allegedly sexually assaulting a child, RadarOnline.com learned exclusively!

Now the arrest of David J. Hughes — a JonBenét blogger who wrote a book about her murder implying the six-year-old enjoyed the attack — could hold the key to finding her killer!

Vermont authorities charged Hughes, 37, with three felonies in December after police found evidence he videotaped a 2014 attack on a three-year-old girl.

Cops said they also found tapes of other attacks where he encouraged two boys, aged 10 and 11, to take off their clothes!

The fiend admitted watching kiddie porn — and authorities are now combing his computer for links to JonBenét’s murder!

“This is an active investigation,” Det. Ryan Ashe of the Rutland, Vt., police department told Radar.

“[Hughes] said he has family out ‘west’ and I plan to reach out to Boulder police to discuss the case.

“If we could establish he was in Colorado or the general vicinity of Boulder, we could develop enough probable cause to get a warrant.”

Insiders told the publication that Hughes’ DNA has already been secretly seized by cops and is being tested.

Hughes was just 15 when JonBenét was found dead in her family home in Boulder on Dec. 26, 1996 — but he’s admitted to an “obsession” with her murder.

“It seems to have consumed most of my life,” Hughes confessed to Radar.

In his book, “An Angel Betrayed,” he implied JonBenét enjoyed the assault.

“[Children] don’t always know it’s wrong, especially if their victimizer is a trusted adult … and most of them want to please adults,” he wrote.

Hughes said he’s communicated with people from Boulder but insisted he played no part in her murder.

“I could tell you I was in no way involved in JonBenét’s death,” he

said.

As Radar has reported, an Indiana woman has fingered her ex-husband, the late Glenn Meyer, as JonBenét’s murderer.

Chillingly, a witness has described a second suspect as Meyer’s accomplice — and Hughes’ arrest warrants a full-scale probe.

“The witness said one of the intruders was in their early teens,” said Roscoe J. Clark, founder of an online group that investigates JonBenét’s death. “[Hughes] fits the profile.”
