Pennsylvania v. Jaleer Fletcher

On February 17, 2023, 18-year-old high school senior Eriq Morrison was gunned down in Chester City, PA. The two assailants discarded their weapons as they fled. A Taurus handgun and an Anderson rifle were recovered. DNA analysis showed six-person mixtures, too difficult for most crime labs to solve.

The prosecutors contacted Cybergenetics for free TrueAllele screening of their “uninterpretable” DNA mixture data. TrueAllele successfully separated the mixture into probabilistic genotypes. Testing references that were provided over time, Cybergenetics connected the weapons to two suspects with match statistics in the millions and billions.

Faced with powerful DNA evidence, one man pleaded guilty. The other man, Jaleer Fletcher, chose to go to trial. Cybergenetics testified about the TrueAllele results. Mr. Fletcher was convicted of second-degree murder and sentenced to 13-40 years in prison.

Weapons are a regular source of DNA evidence. They routinely produce mixtures with five or six people. Most DNA labs cannot solve such complex data, and report “no interpretable results were obtained due to the complexity of the mixture” using the tools they have.

But mathematically advanced TrueAllele interprets mixtures containing 5, 6, or even 10 contributors. Cybergenetics complements the crime lab by taking your “uninterpretable” DNA to the next level and producing the evidence.
