Case #1: On July 3, 2014, 15-year-old Ruby Rubio was walking with her sister in Santa Ana when a man approached and asked her for the time. Ruby pulled out her phone to see the clock, but the man grabbed the phone and ran away - Ruby chased the man who got into a waiting car. As the car sped away Ruby jumped onto the trunk lid and held on, the driver swerved until Ruby was thrown off the car. She landed on the pavement and later died at a hospital. Case #2: We follow up on the Danah Rojo-Rivas murder with new information and a one-on-one interview with Danah’s mother. Case #3: We get a firsthand look at the LA County Crime Lab and speak with the lab’s director about DNA and the role it plays in solving cold cases.
