In December 1990, an eight-year-old boy named Kevin McCallister was accidentally left behind when his family departed for a holiday trip to Paris, leaving him alone in their Chicago home. What began as a case of parental negligence soon turned into a nightmarish standoff. Two local burglars, Harry Lyme and Marv Murchins, targeted the McCallister residence, unaware that the young boy inside was preparing to defend it by any means necessary. Over several hours, Kevin constructed a series of elaborate and dangerous booby traps, inflicting severe injuries on the would-be intruders before police arrived. Authorities later described the scene as chaotic and violent, with evidence of extreme improvisation and intent to cause harm. The case, though ending without fatalities, sparked debate about child endangerment, vigilantism, and the blurred line between self-defense and overkill in suburban America.
