Tennessee v. Bean

“Obsession which led to murder” – District Attorney General Robert Nash

This Montgomery County Tennessee homicide case found critical DNA in highly probative evidence. A cell phone taken from the crime scene and left on the highway. A black ski mask seen on the intruder by the victim’s girlfriend. A knife used in the stabbing and shooting.

The crime lab couldn’t solve the DNA mixtures. But TrueAllele easily did. It found DNA from both defendant John Bean and his victim mixed together on the abandoned cell phone. And they were both on the knife. Bean was on the ski mask.

Finding defendant and victim together on the same items can be compelling criminal evidence. On April 7, 2026, having heard Cybergenetics casework supervisor William Allan testify the previous day, the jury convicted Bean of first-degree murder.
