This episode details the brutal 1994 homicide of Missy Grubbs, a nineteen-year-old college student found in her burned Arlington apartment. Detectives originally focused on three workplace associates with various motives, including a boyfriend and a volatile former coworker, but DNA evidence eventually cleared them. The investigation shifted after the victim's mother identified a neighbor named Luis Aroyo, whose suspicious knowledge of the non-public crime scene details raised red flags. Further inquiry revealed that Aroyo staged the arson to hide a violent sexual assault and murder. Although he initially feigned innocence, a confession and forensic matches led to his conviction. He ultimately received a life sentence for the capital murder of the young honor student.
