Yeah, well if a toddler bed had any blood or smell of death, it wouldnt float very long, especially if tied down with bricks, but because I know we do not know for sure a mattress was missing, its all kind of moot. I personally wish more sleuthing was done on where Hope and Katrina resided.
Well as I see it a person wouldn't really be able to throw a cinder block any significant distance away from the dock so IF anything was tied to the cinder blocks it would still land near the boat ramp..JMHO
