| Crime |
In April 2012, Carnell Marshall died in a vacant Syracuse, NY parking lot. He was brutally beaten and stripped by two men. |
| Evidence |
A beer can was found in a trashcan behind Swift’s house. |
| DNA |
The Onondaga County crime lab developed DNA data from the beer can, finding a mixture of DNA from at least two people. |
| Match |
The crime lab could not produce a match statistic from the can’s mixture data. A DNA statistic was needed for court. |
| TrueAllele |
TrueAllele found Marshall's DNA on the beer can. The computer also connected the can to Lewis Swift with a match statistic in the trillions. Swift was suspected of ordering Marshall’s attack. |
| Cybergenetics |
On January 15, 2015, Cybergenetics Dr. Mark Perlin testified before an Onondaga County jury. |

On January 22, the jury found Swift guilty of manslaughter. He was sentenced to serve 25 years in prison. |
