Commonwealth of Pennsylvania v Tyrell Christian
Homicide: TrueAllele results presented in York County
| Crime | On September 27, 2022, officers responding to a reported shooting found Ethan Mooney unresponsive on the street with gunshot wounds. He later passed away at the hospital. |
| Evidence | Police collected five spent 9mm cartridge casings from the scene. At a later date, police collected a handgun that was used in the shooting. |
| 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 lab could not interpret the handgun data due to the complexity of the DNA mixture. |
| TrueAllele | TrueAllele interpreted the low-level and complex DNA data. The computer calculated exclusionary match statistics of one over 4.17 thousand (cartridge cases) and one over 2.8 million (handgun). |
| Cybergenetics | On October 2, 2024, Cybergenetics analyst Kari Danser testified, for the first time, before a York County jury about the TrueAllele DNA results. |
| Outcome | The jury found Tyrell Christian guilty of first-degree murder and possession of a prohibited firearm. He faces a mandatory sentence of life in prison for the first-degree murder conviction |
