On May 26, 1992, 13-year-old Brandy Myers was collecting pledges for her school’s Read-A-Thon in her Phoenix, Arizona neighborhood. She didn’t return, and soon a search commenced. Though the body of a young girl was found two days later— it wasn’t Brandy’s. It was then that police realized something larger may have been going on in this neighborhood near the Central Arizona Project Canal. Over the next year, two more bodies appeared, though no sign of Brandy ever turned up. This mystery would span the next two decades until cold case detectives made a huge break. Now, Brandy’s sister, Kristin Thelen, is fighting every day to bring justice to her big sister and the other young women and girls who all may have been targeted by the same serial killer.
