For police, determining whether a body pulled from a lake is the result of accidental drowning or something more nefarious can be tricky. That determination becomes easier if, say, the deceased person’s pockets are full of rocks.KOMO reports that such a person was pulled from Spanaway Lake on Sunday morning.”We’re treating it as a homicide until something tells us differently,” said Pierce County Sheriff’s Office spokesman Ed Troyer.The rocks in the pockets may immediately smack of homicide. But Troyer also admits the possibility that the stones may have been used to help the man commit suicide. At any rate, the rocks–if used to weigh the body down–apparently did a poor job of it, as the corpse was noticed by someone walking on the beach who saw it floating on the surface of the water.Investigators will now have to identify the body–he was found without ID and there were no recent missing person’s reports matching his description–then find out how the rocks got in his pockets.Follow The Daily Weekly on Facebook and Twitter.
