CCTV Footage Reveals Twisted Love Triangle Gone Horribly Wrong _ True Crime Documentary

A true crime documentary where CCTV footage unravels a fatal love triangle. In one case, a 19-year-old woman was captured on camera fleeing her boyfriend's apartment after he was fatally stabbed, but her lack of wounds and a suspicious timeline quickly made her a suspect. She then led police to the alleged killer, another man caught on the same CCTV footage walking into the building. Detectives used the footage to establish a timeline, contradict the suspect's story, and expose a motive of jealousy and obsession. When investigators played the footage during interrogation, the suspect's story collapsed.
