In the 21 years since JonBenét Ramsey was sensely murdered, society has been captivated by her case. But despite endless speculation, countless television specials, and more, we’re left with more questions than answers when it comes to her case. But still, that hasn’t stopped followers of the case from closely following and pouring over every aspect of the murder — hoping to unlock something that may provide the answers that the late six-year-old deserves so many years after her death.

And despite the main theories suggesting that a loved one was responsible for her death — either at the hands of her parents, Patsy and John, or her then nine-year-old brother Burke — many believe that an intruder broke into the Ramsey’s home on Christmas day and killed the little girl. And getting to know more about the Ramsey’s home in Boulder could explain how an intruder tragically had access to the house and the opportunity to kill JonBenét.

Patsy and John last saw their daughter alive when the put her to bed the night of Christmas. The next day — hours after Patsy called police to report that her daughter had been kidnapped — John discovered her body in the basement, where she had her mouth duct taped shut and a garrote around her neck.

The presence of a ransom note — which has been highly scrutinized during the past two decades — and the gruesome way JonBenét was discovered prompted many to believe that an intruder, outside of the family, commited the horrific crime. The lack of forced entry puzzled investigators, who later discovered that there were many ways for an outsider to enter the house in Boulder, CO. Not only were there two windows left ajar (allowing cords for outdoor Christmas lights to reach indoor outlets), but there was also a broken window leading to the basement, where the body was found, allowing a stranger to enter without causing too much commotion. John later told the police that he broke the window himself once when he was locked out of his house.

Though it was initially ruled “impossible” to have an intruder enter through the window (it’s still unlear how long it had broken), retired detective Lou Smit presented new evidence that could prove an intruder did enter through the broken window. Part of the evidence he presented last year as part of a televised special was a suitcase under the window that had an unidentified footprint on it, as well as proof that a grate over a window-well had been moved.

While many people subscribe to the intruder theory — pointing to the above information as “proof” — no intruder (or any killer) has ever been found. And it’s likely that no one will ever be found, because when John Ramsey moved his daughter’s body, he compromised potential evidence that could’ve been linked to the killer.

Six months after JonBenét’s death, the Ramseys left Boulder and relocated to Atlanta. Today, the Ramsey’s house isn’t remembered as the site of a murder. To Carol Schuller Miller, who bought the house in 2004, it’s simply home.
