Officials said the next generation of FBI identification software, now being used by the Department of Justice, is allowing investigators to identify partial prints like Cynthia’s.

Vacaville PD said the DOJ recently ran her partial prints through a database of newly uploaded legacy records, which included arrest records from the early 1980s when Cynthia was arrested for petty theft.
