Tsai Lian Veronica Yu was a 30-year-old student at the Art Center College of Design in Pasadena who was killed on March 17, 1985, in Monterey Park, California. According to reports, in the early morning hours she was stopped while driving home at 500 N. Alhambra Road, dragged from her car, and shot to death by Richard Ramirez, later identified as the Night Stalker. Her murder became one of several linked to Ramirez during a spree of murders, sexual assaults, and burglaries across Southern California in the mid-1980s.

Ramirez was arrested on August 31, 1985, and charged with multiple counts of murder and other offenses, including the count for Yu. The case against Ramirez drew national attention through the ensuing investigation and prosecution.
