Who killed Carla Walker? In February of 1974, 17-year-old Carla Walker was abducted after attending a Valentine's Day dance with her boyfriend. Three days later, her body was found inside a cold, dark culvert near Benbrook Lake in Tarrant County, Texas. After an exhaustive investigation, the police were unable to solve the murder and Carla’s case went cold. Very cold. 46 years would go by before a new team of detectives could uncover the truth about her murder and finally get justice for Carla Walker.
