Extended Logline:
“IMPACT x Nightline” examines the unsolved mystery of Kristin Smart, the 19-year-old Cal Poly freshman who disappeared in 1996 after leaving an off-campus party with fellow student Paul Flores.

Now, as investigators execute a new search warrant at the home of Flores’ mother, Susan Flores, renewed hope emerges that advances in technology and investigative techniques could uncover the truth.
