JonBenét Ramsey is the six-year-old victim whose unsolved 1996 murder in her Boulder home has fueled decades of investigation, media scrutiny, and competing theories. Her body was discovered by her father John Ramsey in the basement wine cellar around 1:00 p.m. on December 26, bound with duct tape over her mouth, a garrote around her neck, and covered by a blanket and clothing body condition. John Ramsey removed the duct tape and carried her upstairs, contaminating the scene handling body. Forensic evidence includes unidentified male DNA on her clothing, under fingernails, in underwear mixed with her blood, on duct tape, and matching touch DNA on long johns, excluding family members DNA evidence 1997 testing 2003 analysis. She connects centrally to family members like brother Burke Ramsey sibling relation, parents John and Patsy; investigators like Lou Smit who noted stun gun-like wounds wounds; suspects including John Mark Karr, Gary Oliva, and Michael Helgoth; Boulder Police, DAs Alex Hunter and Mary Lacy who exonerated the family based on DNA exoneration; and theories like the CBS documentary alleging Burke struck her over pineapple theory evidence.
