In 2003, Tiffany Rowell and three of her friends were brutally murdered in their affluent Clear Lake, Texas neighborhood and the crime scene yielded little evidence. The next-door neighbors had seen two young people dressed in black walking nearby and their descriptions were used to create composite drawings, which become a key element in solving the crime. Eventually, an anonymous tip pointed police to a former friend to three of the victims named Christine Paolilla and her then-boyfriend Christopher Lee Snider.
