Sister of missing mom Stacy Peterson says she found body using sonar, cops searched but found nothing

"Twenty-two days after my sister went missing, I had live sonar – full flesh female figure – my sister in the water," Stacy's sister said. “The currents, the wakes, the buoyancy – all the stuff I studied. I figured it out with my better equipment and education where she washed up. And I'm not going to stop. If you want it done right, you have to do it yourself.”
