People of New York v Dequan Grimes
Computer connects convicted offender to illegal handgun
| Crime | In August 2017, convicted offender Dequan Grimes was stopped for speeding. A handgun was found in his vehicle. |
| Evidence | The handgun was swabbed. |
| DNA | The Suffolk County crime lab developed DNA mixture data from the handgun. |
| Match | Due to the complexity of the data, the crime lab was unable to draw conclusions from the evidence. They recommended using “probabilistic genotyping” for further processing. |
| TrueAllele | On the same DNA data, the computer’s statistic connecting the handgun with Grimes was 130 thousand. |
| Cybergenetics | On June 28, 2018, Cybergenetics forensic analyst Beatriz Pujols testified at the trial in Riverhead, NY about the computer DNA match statistic. |
| Outcome | On June 29, 2018, Dequan Grimes was found guilty of criminal possession of a weapon. |
