Planted Evidence _Forensic Files _ FULL EPISODE

🔍 "We were the first criminal case in the country that used a DNA comparison of plant material."In 1992, the body of single mother Denise Johnson was found beaten and strangled outside Phoenix. The only lead was a pager belonging to trucker Mark Bogan. Detectives found seed pods in his truck and matched them to a tree at the crime scene using DNA. This groundbreaking technique—the first of its kind—convicted Bogan of first-degree murder and proved that plants can be silent witnesses.
