The autopsy report on the remains of little Lucas Hernandez suggests we may never really know what happened to the 5-year-old Kansas boy, but Dr. William Morrone, a pathology expert, sees a major clue in a chemical detected in his liver.

Morrone shares his observations about the autopsies on Lucas and his step mother Emily Glass with Nancy Grace. We also hear the 911 call Glass made to report the child was missing from his Wichita home last February and the recent 911 call his dad made after finding Glass shot dead in the same home.

Also on Grace’s show offering insight about the new clues in this tragic mystery are forensics expert Joseph Scott Morgan, Atlanta prosecutor Kenya Johnson, New York psychologist Caryn Stark, and Atlanta juvenile judge and lawyer Ashley Willcott.
