13-year-old Brenda Sue Davidson disappeared from Woodbridge, Virginia, on March 4, 1974. Her little sister, Lisa, was just seven at the time. She grew up believing that Brenda ran away. When Lisa grew up, she decided that she wanted to find her sister. When she began asking around, the stories didn't seem to make sense. She started to wonder if her father's abuse had gone too far and if the runaway story was a cover-up. 

Lisa desperately wants answers and is looking for anyone who may have known her family back then. 

If you have any information about the disappearance of Brenda Sue Davidson, please call the Prince William County Sheriff's Office at 703-792-6500 or 1-800-THE-LOST.
