Dateline

For the second week in a row, NBC’s Dateline will profile an unspeakable crime committed in Idaho.

Things changed so quickly in the Lori Vallow murder trial that all NBC could crank out in time for this week's episode was this 20-second teaser from Keith Morrison.

National news magazines are churning out episodes about the horrific murders of Kaylee Concalves, Madison Mogen, Xana Kernodle and Ethan Chapin.
