Teen barista girl Samantha Koenig falls victim to sick serial killer

Samantha Koenig was kidnapped at gunpoint from the Anchorage, Alaska, coffee stand where she worked as a barista in February 2013 by a man who may be one of the most prolific serial killer in U.S. history. Israel Keyes, who later admitted to killing 11 people across the country had developed an elaborate plan to demand a ransom for the 18-year-old's return. Former FBI Special Agent Bobby Chacon, who led a dive team that recovered Koenig's dismembered body from a frozen lake two months later, joins Nancy Grace in an exploration of the case. The expert panel also includes Cold Case Research Institute Director Sheryl McCollum, Atlanta juvenile judge and lawyer Ashley Willcott, Los Angeles psycho analyst Dr. Bethany Marshall, and Crime Stories Reporter Robyn Walensky.
