The Runaway Theory

Two human feet washed up on the shore by Benton Cliffs five months after Russell went missing. Both of the feet were tested in 2010 and neither of them belonged to Russell. Do you think they tested the feet thoroughly enough or do you think maybe they should retest them? I mean, we've already seen that the police work in this case is pretty rubbish, so it wouldn't surprise me if they didn't put a hundred percent effort into testing these feet.
