When LE declared this case a criminal investigation, and I began to worry & suspect that perhaps Ky was no longer alive, my first thought was that if someone had ended his life, and that person wanted to dispose of evidence, the Columbia River seemed like a likely place to do so. It has stronger currents than the Multnomah Channel, and I began to wonder if any evidence would have been quickly carried out to the Pacific Ocean.
I fear that if our little guy is no longer alive, and if he was put into the Columbia River and carried out to sea, then he may never be found. If so, this could be why his body has not been found.
I don't like to ponder that scenario. But every now & then I think about it as a possibility of what may have occurred.
