The murder of JonBenét Ramsey remains officially unsolved. JonBenét, a six- year-old child beauty pageant winner, was found dead in her family's home in Boulder, Colorado, on December 26, 1996. Her death was ruled a homicide caused by asphyxia due to strangulation and a skull fracture

. The investigation initially focused on her family, including her mother Patsy Ramsey and father John Ramsey, due to a ransom note and the circumstances of the crime scene. However, no charges were ever filed against them, and her brother Burke, who was nine at the time, was also cleared as a suspect

. An alternative theory supported by some investigators, including detective Lou Smit and former FBI agent John E. Douglas, posits that an intruder entered the home through a broken basement window and killed JonBenét. This theory is supported by unidentified DNA evidence found on JonBenét, which has not matched any family members. The father, John Ramsey, believes that DNA evidence could eventually identify the killer

. No one has been officially arrested or convicted for JonBenét's murder. Various suspects and theories have been proposed over the years, including claims by individuals confessing to the crime, but none have led to a definitive resolution

. In summary, while the Ramseys were initially suspects, the current prevailing theory supported by some experts is that an unknown intruder killed JonBenét Ramsey, but the case remains open and unsolved.
