| Crime |
On November 15, 2019, police discovered two people dead following a home invasion robbery at a home on Dandelion Drive. The victims included a resident of the home and one of the suspects. Investigators determined that three men were responsible for the homicides. |
| Evidence |
The crime scene team collected swabs from a gun found at the scene and a victim’s T-shirt. |
| DNA |
The Tennessee Bureau of Investigation generated DNA data from the evidence. |
| Match |
The crime laboratory was unable to interpret the gun evidence due to the complexity of the data. The lab also reached inconclusive results for the t-shirt minor mixture contributors. |
| TrueAllele |
On the same data, TrueAllele connected the evidence to all three suspects. The computer calculated an inclusionary match statistic between the pistol grip and suspect Richard Woodson with a match statistic of 210 thousand. The error rate for this match statistic is 1 in 57.8 million. |
| Cybergenetics |
On January 23, 2023, Cybergenetics casework supervisor William Allan testified before a Montgomery County jury about the TrueAllele DNA results. |
| Outcome |
On January 30, 2023, the jury found Richard Woodson not guilty of first-degree murder and aggravated burglary. |
