This three-chapter true crime forensic series examines the murder of Zhifan Dong, a Utah college student killed in twenty twenty two by her boyfriend after multiple reports of domestic abuse failed to trigger effective intervention. Told in a neutral, investigative voice, the story traces the final days, the warning signs that were documented but fragmented across systems, and the aftermath that followed her death. It is not a mystery about who committed the crime, but a case study in how institutional gaps, procedural limits, and isolated decision-making allowed a visible risk to escalate unchecked.
