“...washed up on the beach a few days later even thouh he was weighted down with concrete blocks.”
Another reason why a wood chipper is a handy tool.
I never go on a killing spree without one.
There was a case where the husband killed his wife, put her in the freezer, and used a wood chipper to dispose of her body early in the morning during a snow storm from a bridge. A witness drove by. He used a credit card to rent the chipper in the relevant time period. The police did a systematic search of the river and seived out remains of bones from the wife. They found portions of some pieces of her skeleton that indicated an unsurvivable wound. The husband was convicted of capital murder.
