FROM BEST FRIENDS TO KILLERS

AIRING ON "20/20 SATURDAY," JANUARY 3, 10 PM ON ABC

Sixteen-year-old Skylar Neese disappeared from her home one summer night, last seen on surveillance video sneaking out of her window and getting into a sedan. What many thought was a typical case of a teenage runway turned out to be something much more wicked - Neese was later found stabbed to death by her two best friends. The police had few leads until a surprising break in the case. Correspondent Ryan Smith interviews Neese's parents, police, and high school classmates to unravel what drove two teens to commit a horrific murder. Anchored by Elizabeth Vargas and David Muir, " 20/20 SATURDAY" airs on SATURDAY, JANUARY 3 (10:00 - 11:00 pm ET) on the ABC TELEVISION NETWORK. (OAD: 7/18/14)
