The case for and against Robert Xie

KEY POINTS IN ROBERT XIE'S MURDER TRIAL

WHAT THE CROWN SAYS

* One person, in the dark, murdered the Lin family at their North Epping home in Sydney's northwest, in the early hours of July 18, 2009

* Xie had access to a key

* No evidence of lock tampering at the Lin home

* Manner of Min and Lily Lin's deaths indicate "intense bitterness and hatred"

* Bloodied shoe prints in Lin home consistent with Asics sneakers Xie wore

* On May 6, 2010, Xie cuts up shoe boxes, showing "consciousness of guilt"

* Small "bloodstain" on Xie's garage floor "most likely" contains DNA of four Lin family victims

* Xie made "implied admissions" to prison informant, Witness A, at Long Bay jail

WHAT THE DEFENCE SAYS

* It wasn't one person in the dark

* Time of death is unknown

* Shoe prints inside the home point to five possible sizes

* Xie had no financial motive for killing the Lin family

* Murders show not hatred but a "cold-blooded slaughter"

* If Xie was driven by hatred towards Min and Lily, why kill them when everyone is at home?

* Disputes DNA evidence and the crown assertion the stain on Xie's garage floor is blood

* Says witness A is a "ruthless prison informer"

* Xie never admitted to Witness A he was the killer
