The question how do you even do that? The squirrel in question was a decorative squirrel made of ceramic. When in shards you can use them to stab somebody, I suppose...
Now the reason why is even more ridiculous. The wife send her husband out for beer, however the stores were closed due to Christmas (doh!), so the husband came home without beer. The wife clearly did not accept this valid reason, and she became outraged, and wacked him with the squirrel first and eventually stabbed him. She later stated to the cops her husband merely slipped and fell onto that squirrel, but as she could not explain why her hands and clothes were covered with blood, she's now in jail...
