I was looking in Bunny's exhibit and findings at exhibit D 212 Kristen's pajamas and read the notes on the cuts to her clothing, pajamas and undershirt. Below is a summary of what was found on the clothing and her wounds.
Pajama top front: 19 cuts, no puncture
Undershirt front: 3 cuts 7 punctures
Wounds front: 4 cuts, (plus 1 on the neck) 5 ice pick (shallow), 12 ice pick (very shallow right side, S shaped)
Three superficial abrasions of the right lateral neck,
Two additional abrasions or peeling away of the superficial skin on top of the right shoulder.
Right hand: cut through on side of ring finger, cut on the palm side of index finger, other small cuts
Left hand: small cuts
Pajama back: 7 cuts no punctures
Undershirt back: 6 cuts, 4 punctures
Wounds: 12 cuts
What is interesting is that there are 19 cuts to the front of her pjs and only 4 cuts to her chest. That means that mac was stabbing the cloth and not reaching her body. The abrasions on her right neck and shoulder were probably from him holding her with his left hand while she was face up in the bed. The cuts on both hand show that she was either protecting her chest with her hands or holding her hands up to the knife blows.
The pj top was full so he was stabbing the cloth while she was moving trying to avoid him. She was probably also also kicking him. He then grabbed her and held her face down so that she could not hold up her hands or kick him. He held her face down into the pillow. The largest blood stain is on her pillow and under it. Some of the cuts in the chest went into the heart. As she fought face down, her hear pumped out blood onto the bed and pillow. She continued to kick and to subdue her he dragged her to the side of the bed.
I think he held her on the side of the bed (in an upright position, with her bent over the edge of the bed) and pinned her lower body with his legs while he stabbed her deeply in the back. The wounds in her front would have been bleeding freely onto the top and edge of the mattress.
Her pajama and undershirt had scrunched up in the fight as there were half as many cuts in the pj back/undershirt as there were wounds in her back. When she was no longer fighting, he stepped away from the bed and her body fell to the floor, smearing blood onto the side of the plastic box spring cover. Her body lay next to the bed and blood dripped onto the floor. Later he picked up her body and placed her on the bed. He used the ice pick on her chest and arranged her in a sleeping position (a classic case of "undoing" the crime) and put the bottle near her face.
While mac claims that he fought off a knife attack and ice pick attack, he had no significant wounds on his hands. Kris had one gaping wound, another cut, and other small cuts.
