In January 1984, 29-year-old Teresa Solecki walked to a payphone in Vista, California, to make a quick call to her sister. She never came back. Hours later, her body was discovered along a remote stretch of Gopher Canyon Road—brutally beaten and strangled.

For decades, investigators held onto the evidence: a bite mark, a drag trail, and an unknown male’s DNA. But without modern technology, Teresa’s case went cold. It would take 35 years, new forensic science, and the power of investigative genetic genealogy to finally reveal the truth—and identify her killer.

This is the story of the murder of Teresa Solecki—and how DNA preserved for decades helped bring justice to her family.
