"You have heard from Dr Carter who talked about the injuries to Lindsay Birbeck's neck, she talked about the sort of force on the neck that was so severe it resulted in cartilege fracture and the sort of force that produced such an extensive crushing damage to an entire larynx.
"And to add insult to injury - a rough cut injury - which Dr Carter estimated was an effort to dismember with something like a saw, to the leg.
"Once she had been killed her body needed to be disposed of.
"Was there a mystery man?
"Or is the mystery man a creation of the defendant's limited imagination.
"He can't or won't help you as to who this mystery man is and the prosecution say he can't because the mystery man is him.
"Imagine you had killed someone, do you ask a random passer-by to dispose of the body without knowing what they would say or do.
"The defendant must think you were all born yesterday.
"There is no mystery male, it is the defendant.
"You heard he is not motivated by money and may do something without questioning why to do it.
"But take into account what his teacher said about doing something without question. But this is not the same.
"In the defendant's world, no really does mean no.
"He was not motivated by money and the promise of lots of money would not mean anything to him.
"And you live in the real world, and that story does not hold water.
"How would he react to a stranger? He would be shy, and wouldn't make eye contact.
"But the defendant is now able to provide details of the meeting in a prepared statement to the police.
"What does that tell you about his ability to communicate?
