It's been more than 20 years since JonBenét Ramsey disappeared from her Boulder, CO home, but now new evidence has emerged in the case. According to Radar Online, murder suspect Glenn Meyer had an accomplice — a suspicion the slain beauty queen's father has thought for some time.

In the bombshell report, the publication claims a second man was spotted fleeing the Ramsey's home, and it's believed he helped Glenn carry out the sexual assault and strangulation of the six-year-old. He was allegedly a tall, slim, white male with brown hair. "There was more than one person involved," JonBenét’s father, John Ramsey, said, citing information gathered by a private investigator.

The disturbing revelation comes after Radar spoke to Glenn's wife, Charlotte Hey, who opened up about her late ex-husband after years of silence. "I believe my husband killed JonBenét. I knew he was capable of it," the now 85-year-old said. "When I asked him if he murdered her, he would just smile at me. He wouldn't deny it."

At the time of the murder, Glenn was living across the street from the Ramsey mansion. He reportedly built a shrine to the murdered child, using pictures and newspaper clippings, sources said. In addition, his handwriting matched the ransom note found in the home.

The note — which promised John Ramsey that his daughter was "safe and unharmed," but threatened to kill the little girl if the note's writer's demands weren't met — was written on stationery found inside the house, which makes it unusual. According to experts, most criminals come prepared with their ransom notes, rather than write it on the fly.

Roscoe J. Clark, founder of the online group JonBenét Investigation, agrees with the idea that someone else was involved. "There's evidence two intruders committed the murder because two unidentified footprints were found at the crime scene." Now the only question is who? And why did it take so long for this information to come to light?
