The Boulder, the Jar, and Alyssa Self’s Killer | Ice Cold Killers | S5 E2

Before sunrise in a frozen St. Louis alley, 11-year-old Alyssa Self vanishes on her short walk to the bus stop. What follows is a frantic citywide search, a chilling phone call, and a discovery 130 miles away that shatters a community. Step into the investigation as detectives brave an ice-locked January of 1991, chase dead-end tips, and weigh suspects who seem perfect on paper but fall apart under scrutiny. Then, in a remote river lot beneath a bridge locals call the Black Bridge, one odd detail changes everything: a freshly chipped boulder. From there, a muffler that shouldn’t be new, a composite sketch that misleads, and a common household jar hiding a microscopic clue converge into a breakthrough few saw coming. This is the story of how patience, forensics, and a promise made at an autopsy table turned a “needle in a haystack” into a name. Watch to see how the smallest signs in the cold led investigators to the truth. Watch now to follow the clues to their chilling end. #AlyssaSelf #StLouis #TrueCrime #IceColdKillers #1991 #Forensics #ColdWeatherClue #Justice
