User webinar - Solving a seven-person mixture
How do you solve a seven-person DNA mixture to find justice? Answer: use TrueAllele.
On April 7, 2014, Cleveland gas station attendant Babul Saha was killed by an armed gangster. Video surveillance footage showed the suspect had a white plastic bag. The crime lab said the bag's DNA mixture was "inconclusive due to too many contributors." But TrueAllele computing solved the 7-person DNA mixture, helping bring defendant Slater Howell III to justice.
On August 14, 2025, Cybergenetics Matthew Legler gave a 45-minute TrueAllele user webinar explaining how the computer solved this impossible (for other software) DNA mixture problem. He showed the challenging DNA data, and how Cybergenetics used TrueAllele. Matt told how "genotype concordance" produces reliable DNA match statistics and error rates. And how relevant validation studies support trial testimony.
On September 12, 2017, the jury found Howell guilty of all charges. He was later sentenced to life in prison for murdering Saha and a Cleveland firefighter.
