Murder victim Paul Murdaugh's 23-year-old girlfriend is featured in a new three-part Netflix documentary about his father's, Alex Murdaugh, murder case. Morgan Doughty says "It was just very normal for them to be drinking and just having a lot of alcohol like always stocked in the house." She also states she had a turbulent relationship with Paul. It comes as Buster Murdaugh's testimony at his father's murder trial became a hot-button topic.
