And how would you know exactly where he went so you could dump them in the bay so they would wash ashore to implicate him?
I don't, to this day, know where the "Berkeley Marina" is. Is that the right name? If it is, I just googled it and I got a map and driving directions.

Doesn't seem like a big problem to me.
