NBC’s Dateline will profile the disappearance and murder of Erin Corwin tomorrow night.

Corwin, who was having an affair with her neighbor, was reported missing two years ago and later found in a mine shaft in Joshua Tree. The man she was having an affair with, Marine Christopher Lee, was found guilty of her murder and sentenced to life in prison without parole in November.
