Who killed JonBenét Ramsey? That’s the question that’s plagued authorities and family members for nearly 22 years. Now, the former beauty queen’s brother, Burke Ramsey, is determined to prove his innocence once and for all — by pressuring investigators for key documents.

According to Radar Online, the 31-year-old served CBS with a whopping $750 million defamation lawsuit for the 2016 docuseries The Case of: JonBenét Ramsey, and his team is pushing for the release of more than 60,000 pages of confidential police and FBI records, DNA evidence, and medical examinations gathered during the investigation.

The Ramsey family attorney, L. Lin Wood, insists: “Burke is innocent.”

Burke’s lawyers say key evidence about the contents of JonBenét’s stomach was deliberately left out of the docuseries in order to frame him. The scenario alleged that a then-nine-year-old Burke was furious at JonBenét for stealing pineapple from his bowl, so he smashed her over the head with a flashlight and killed her.

But Burke’s lawsuit claims the pineapple found in JonBenét’s body was in the intestinal tract below her stomach — meaning it had been eaten two to three hours before she died. Additionally, grapes and cherries were found in her system, which the series failed to disclose.

Experts — who testified in the case — said JonBenét would have died within three minutes of a blow to the head, so she wouldn’t have digested the pineapple. In other words, the docuseries’ theory is impossible.

On Christmas day in 1996, JonBenét was discovered sexually molested and strangled to death in the basement of the family’s Boulder, CO home. Although many people have been associated with her murder, the case is still open.

The Boulder District Attorney’s office supported the theory that JonBenét was killed by an intruder, with a broken window in the basement and the gruesome way she was killed (suffocated by a garrote) listed as potential “evidence.”

However, the alleged intruder/murderer has not been found; in 2006, elementary school teacher John Mark Karr falsely confessed to the pageant star’s murder, but DNA samples provided by him did not match the DNA samples found on the child’s body.

In Summer 2016, In Touch revealed that Michael Vail tipped off police about his high school friend Gary Oliva — a pedophile with a strong connection to the case — calling him days after the 1996 murder confessing that he “hurt a little girl.” To this day, though, who truly killed JonBenét remains unsolved.
