Witness: Aaron Hernandez's DNA found on marijuana joint at murder scene

FALL RIVER, Mass. (AP) — A crime lab scientist testifying in the murder trial of former New England Patriots tight end Aaron Hernandez has testified his DNA matched that found on a marijuana joint at the crime scene.

Diane Fife Biagiotti of the Massachusetts state police crime lab testified Friday.

Hernandez is charged with murder in the June 2013 killing of Odin Lloyd, who was dating the sister of Hernandez's fiancee.

Lloyd's body was found in an industrial park near Hernandez's home. Prosecutors had said previously a marijuana cigarette was found near his bullet-riddled body.

Biagiotti says she was able to deduce Hernandez's and Lloyd's DNA were on the butt.

She says the statistical likelihood it was someone else is one in more than a quadrillion.
