When the 3-year-old endangered orca washed ashore in Washington state battered, bloodied and bruised in February of 2012, her death fueled a mystery over what killed her. Two years later, investigators say they don't know for certain what caused blunt force trauma to the animal's head and neck. (AP Photo/Sandy Buckley, File)
