The unsolved 1996 murder of 6-year-old beauty pageant queen JonBenet Ramsey in her family's Boulder, Colorado home has continued to grab the attention of the nation nearly 30 years later.

Now, the young victim's half-brother has come forward to speak publicly about the horrific loss and the grief the family has endured ever since that fateful day, according to the Daily Mail.

John Andrew Ramsey addressed the false narrative that one of his family members murdered the little girl, was critical of how police and the media handled the case, and offered his theory on who the real killer might be and how the brutal incident occurred.

The JonBenet Ramsey murder mystery

It was last month that Netflix premiered a new three-part docuseries titled "Cold Case: Who Killed JonBenet Ramsey?" that aims to expose how "police missteps" and a "media circus" worked to derail the murder investigation, as well as document the family's unending quest to find justice.

That Netflix series has sparked a renewed public interest in the mysterious death that was discovered on the day after Christmas in 1996, when JonBenet's battered and lifeless body -- she'd been sexually assaulted, bludgeoned, and strangled to death -- was found in the home's basement.

Boulder Police for more than a decade viewed the family -- specifically father John and mother Patsy, along with then-9-year-old brother Burke -- as the primary suspects in the brutal slaying, only for them to eventually be cleared of suspicion by DNA evidence in 2008, albeit after Patsy had died from cancer.

Half-brother focused on solving the mystery

In an exclusive interview with the Daily Mail, JonBenet's half-brother John Andrew, who was 23 at the time of her death, took great exception to the years of fingerpointing at his family and said, "If I'd thought for a minute my father or Patsy or Burke was capable of murder, I'd have flipped on them in a heartbeat."

"There's someone out there who knows something that could help catch my sister's killer," he continued. "The narrative is that this is an unsolved homicide. We want to keep the pressure on law enforcement and encourage anyone who might have information to come forward."

Though he was hesitant to provide too many details about his own life and family, he did share how he'd given up his career to focus his efforts on solving the mystery, and said, "As crazy as it sounds, it's a full-time job."

Who does he think the real killer was?

JonBenet's half-brother also had a message for those who still believe that her parents and brother were responsible for her death, as John Andrew said, "To the people who think Dad and Patsy killed JonBenet in some crazy accident and tried to cover it up ... are you telling me that they sat in a room with the police for nine hours and kept up this ruse with their daughter lying dead on the floor below? No way."

"JonBenet was tortured," he continued. "Anyone who's seen the autopsy photographs and the deep injuries to her neck will tell you she was tortured. The idea that Dad and Patsy would do that is unimaginable. What happened fits the profile of a sadistic pedophile."

"I think the killer entered the home when the family was out to dinner and waited -- and if you look at the behavioral characteristics of a sadistic pedophile … they stalk their victims," he offered up as a theory, and added, "I don't think the killer actually knew my father, but I think he was jealous of his success and if you couple that with a sexual perversion -- the way to hurt my father was through JonBenet."

Boulder PD insist JonBenet murder case remains a "priority" for investigators

As noted, the Boulder Police Department still hasn't solved the case but recently released an update on the investigation, in which Chief Steve Refearn said, "The killing of JonBenet was an unspeakable crime and this tragedy has never left our hearts."

"We are committed to following up on every lead and we are continuing to work with DNA experts and our law enforcement partners around the country until this tragic case is solved," the chief added. "This investigation will always be a priority for the Boulder Police Department."
