The really sad thing here is, the smiley faces look nothing alike, and are not even at the right places. The detectives are "guessing" the smileys are located at or near where the body was dumped, but needless to say, proof is lacking. As with all conspiracy theories, the answer seems rather simple, to all but a few. I suppose I would be "looking at all the possibilities" if it were my son or relative who drowned, but when they have blackout level BAC and the campus is a few blocks from the river, goodness, it's a 5 minute Murder She Wrote. Tragic things happen to those who abuse alcohol and drugs. I'm not sure why folks are trying to figure out the obvious.
