B: Eileen Jane Snow. Lady she carpools with couldn't get her to answer the door. Police broke in.
G: This is exactly the same as the last two.
B: Audrey Hayes __①__.
G: Different M.O., __②__.
B: M.O. is how he breaks in. Signature's what he does once inside.
G: Three or four overpowering blows to the head from a homemade weapon fashioned at the scene. Forces her to drink a mixture of sodium amytal as a chemical restraint. Overligature of the victim ... and an object rape. Then he strangles her. Ejaculates on the bedsheets. __③__.
S: Damn it.
S: Damn that guy.
G: Listen, __④__.
S: __⑤__, Grissom.
