And they want everyone to keep talking and not lawyer up, so they don't want anyone to be declared a suspect, because that is when they lawyer up. LE also needs a body. Once this eventually hits a jury, no body is harder to prove a crime. If you have a body, usually you can find cause of death, then you might find a murder weapon. Lots to gain from getting a body. Anyone remember Kyron Horman case? Never found; stepmother did it IMO. LE never could bring charges because they really needed more physical evidence. (I lived just a few miles from where he disappeared and followed the case very, very, very closely. I worked out at the gym that they went to. For years the gym still had a fence with Kyron's picture, balloons, and flowers for him....)
