Abstract

Commonwealth v. Foley was a landmark case in the history of DNA evidence. It was the first time that an advanced statistical computing method for interpreting DNA mixtures was ever:

1. used as evidence for a criminal case;
2. admitted into evidence after an admissibility challenge;
3. introduced as evidence in a trial;
4. upheld as reliable evidence by an appellate court; and
5. established as a statewide precedent.

Dr. John Yelenic was brutally and tragically murdered, but the trial that convicted his killer bequeathed to society a powerful truth-seeking technology for bringing criminals to justice.
