On December 26, 1996, 6-year-old beauty pageant JonBenet Ramsey queen was found murdered in the basement of her Boulder, Colorado, home. She had been hit on the head and strangled with a crude garrote. She also showed signs of sexual assault.

Seven hours before the shocking discovery, JonBenet’s mother, Patsy Ramsey, called police and reported that her daughter was missing and that she had found a ransom note demanding $118,000 in cash.

No one has ever been charged in the case, and the investigation is still open. Early suspicion fell on her parents, but they were exonerated after DNA at the scene was found to belong to a male unrelated to the Ramsey family.

Why has the case remained unsolved? There’s no single explanation, though authorities readily acknowledge that early missteps by police hampered the investigation for years.

Intense media coverage at the time also played a role, pressuring police to act quickly and sending investigators down ultimately useless paths.

Just as some people still obsess about the assassination of President John F. Kennedy, some still study the JonBenet case relentlessly and offer up theories about her killer.

Who do you think was responsible for JonBenet’s murder?
