Teresa Lyn Terry Wallin was 22 and three months pregnant when she was murdered on January 23, 1978, in Sacramento, California. The scene was described as showing organ removal and evidence that the attacker drank blood.

This killing was one of six murders attributed to Richard Trenton Chase, later called the Vampire of Sacramento. Chase was said to have a long history of severe mental illness, including schizophrenia and hypochondria. Investigators led by Lt. Ray Biondi gathered evidence and witness testimony that contributed to Chase’s identification and arrest; he was charged with multiple counts of murder and later found guilty.

Does anyone have memories of Teresa, her family, or information about her life in Sacramento that could help preserve her story?
