Commonwealth of Pennsylvania v Tyrell Christian

Homicide: TrueAllele results presented in York County Courthouse

Crime On September 27, 2022 Ethan Mooney was found unresponsive on the street with gunshot wounds. He later died at the hospital.
Evidence Five spent 9mm cartridge casings were collected from the scene. A handgun was found at a later date.
DNA The Pennsylvania State Police Bureau of Forensic Services generated informative DNA data from the evidence items.
Match The crime lab concluded that the cartridge data was uninterpretable due to an insufficient quantity of data. The handgun data could not be interpreted due to the complexity of the mixtures.
TrueAllele TrueAllele was able to interpret the data. When compared with Tyrell Christian the exclusionary match statistic was one over 4.17 thousand.
Cybergenetics    On October 2, 2024, Cybergenetics analyst Kari Danser testified before a York County jury about the TrueAllele DNA results.
Outcome Tyrell Christian was found guilty of first-degree murder and possession of a prohibited firearm.
