HEAR 5-year-old Lucas Hernandez 911 call

PLUS: New Thriller ‘Last Time I Lied,’ Riley Sager

Investigators sometimes refer to 911 call recordings as a “Christmas tree” because of the many clues it gives them to help solve a crime. Nancy Grace unwraps the gifts delivered in the call Emily Glass made to report her stepson Lucas Hernandez was missing from their Wichita home in February and the call Jonathan Hernandez made after he found Glass shot to dead in the same house last month. Helping with the unwrapping are body language and verbal expert Susan Constantine, Atlanta juvenile judge and lawyer Ashley Willcott, and private investigator Vincent Hill.

CrimeOnline’s investigative reporter Leigh Egan updates the condition of Jonathan Hernandez who fell critically ill after his son’s memorial service over the weekend.
