Abstract

In 2016, a Northern California county accused 22-year-old Manuel Lopez of raping and murdering his girlfriend's toddler son. On the surface, the crime laboratory's abundant DNA evidence seemed to implicate Lopez in the capital crime. But the lab's partial data analysis was wrong – Lopez was innocent. TrueAllele® in-depth computer reanalysis of seventy-five mixture items revealed the forensic truth that set Lopez free.

Science is the search for truth, based on testing theories with data. For over twenty years, most crime labs have followed failed FBI analysis methods. Their limited and biased DNA analysis has derived incomplete, incorrect, and inconclusive results that harm innocent people. Millions have suffered from unscientific DNA failure. TrueAllele corrects these errors.

This ninety-minute talk explores the role of truth in forensic science. California v. Lopez – and other cases – highlight the well-known failures of limited FBI methods. By contrast, Cybergenetics' more thorough computer testing finds truth in DNA evidence. The automated TrueAllele system doesn’t take sides, it just weighs DNA evidence. Accuracy and objectivity deliver better justice through better science.
