This week’s episode of Grave Mysteries was an unusual story of an unlikely victim of prostitution and a violent murder. Brittany was a model high school student who worked with younger kids at the local rec center. When she vanished after taking a trip to the store, her family became concerned. Their concern turned to panic when night fell and she still wasn’t home. They called the police. There were concerns about Brittany’s older boyfriend, Derrick. They didn’t approve of him and suspected he had done something to Brittany. The investigation depends upon Facebook and phone record searches to find Brittany’s killer. And, in a terrible twist, she isn’t the only victim.
