*** Content warnings: Child sexual assault, child murder ***

In 1986, two pre-teen girls from Tacoma, Washington, were abducted and murdered mere months apart. Both Michella Welch and Jennifer Bastian were attacked, sexually assaulted and killed after cycling to a public park. Their crime scenes were eerily similar; both bodies were hidden in wooded areas, and the girls even looked alike. Investigators were quick to rule the slayings were the work of a serial killer… But it would take more than 30 years for the shocking truth to come out.
