Young woman was found dead in a park in Seville, Spain. Police thought she died of a drug overdose and released the crime scene. That’s when Carmen Moreno stepped in. She had worked cleaning up the park for many years, and was charged with disposing of a pile of bloody tissues left behind. But Moreno thought there was too much blood to be explained by a drug overdose. And she was a fan of the TV show CSI: Crime Scene Investigation.
Following what she saw on TV, she demonstrated how she used plastic bags to carefully collect the evidence without contaminating it and stored it -- just in case police ever needed it.
When an autopsy later proved the woman likely died from being violently raped, police couldn't believe they tossed vital evidence and were more stunned to learn Moreno held on to it.
