The Dr. Di Maio, says that her wounds are defensive wounds. It is very hard to cut someone's throat while they are laying down and you are sitting on their waist with one hand your left pinning both wrists together. The only direction darlie can go with her arms is up and up with her head. This makes it harder to get a fatal wound on her. The neck is bent forward and the muscles are taunt. The arms are trying to get free and the stab wounds show a pattern of going for a fatal area. When her arms deflect one wound straight at the heart, the attacker goes for her heart again, but is deflected sideways and gets her shoulder area instead, giving up on the heart the next one is a slashing not stabbing move to her throat. Her upwards movements trying to dislodge her attacker are most likely what saved her life.
