Birmingham sisters murder: Man convicted of murder
Mr Crigman said: "It is a certainty that where you see those girls is not where they were attacked or killed.
"They were attacked in the lounge of the flat and they were dragged, dead or dying... and extremely likely already dead, into the bedroom."
The prosecution barrister detailed the wounds the sisters had suffered, revealing that Sabrina's injuries from a series of "precision strikes" had led to the loss of all the blood in her system.
The younger victim was stabbed 32 times by Ali, who claims to be from Iraq but told friends he is Moroccan.
Yasmine had also undergone "a beating", Mr Crigman said, suffering wounds to her arm and wrist and an 8in deep stab wound to her back which entered her heart.
The sisters were last seen alive at 10pm on September 13 2008.
Their bodies were found after relatives became concerned that they had not been in touch.
CCTV images seen by the jury show Ali leaving the apartment with a carrier bag - thought to contain his bloodstained clothes - at about 1pm on Sunday September 14.
He was arrested two days later at Dover docks in what the prosecution claim was an attempt to flee the country.
The killer - described as a "monster" by detectives - had denied murder but pleaded guilty to manslaughter at a hearing in March, claiming he was provoked into doing what he did during a loss of self-control.
But Mr Crigman told the jury: "It's not a case of him being provoked - it will be a case of him not getting something he wanted or something not going his way... or losing control of the relationship, as he probably was at this time.
