Watch the Dateline episode “Dark Intentions” now

It’s the call everyone dreads. The one in the middle of the night. For Hiep Vu, it came in September 1996. It was his sister Christine’s boyfriend, Thang Khuu. He was frantic on the phone. Somebody had killed Christine. Thang found her body in her bathtub at the Pear Tree Apartments in Arlington, Texas. Investigators were at the scene shortly after. The race to find Christine’s killer was on. And then, just a few months later... Another murder. Wendie Prescott. Her body was found in the same apartment building. Also in her bathtub. Could investigators solve their cases before the attacker struck again? Watch the full episode “Dark Intentions” on Peacock now. You can also watch on the NBC app or listen to it on our podcast.
