"VERY LITTLE" weight should be placed on some evidence that mother Teah Rose Luckwell and her accused killer may have had grievances between them, a court has heard.
Public defender Stuart Bouveng began his closing address on Tuesday in Jesse Leigh Green's judge alone hearing in the NSW Supreme Court.
Green is accused of stabbing Ms Luckwell, 22, in the neck and back inside her Robert Street flat in the early hours of March 28, 2018.
Mr Bouveng said the Crown case is entirely circumstantial and told the court his ultimate submission would be that police investigations had not "excluded" all other reasonable possibilities besides Green.
He said there was no evidence of forced entry to the unit and no defensive injuries found on Ms Luckwell.
He said the Crown's submission that it was not a coincidence that the murder happened on the same morning a door was allegedly stabbed nearby was an attempt to put forward a reason for Green to kill Ms Luckwell.
"The reality is there is no evidence of motive," Mr Bouveng argued.
Ms Luckwell and Green had been neighbours in the Homes North social housing units on Robert Street and the court previously heard that Ms Luckwell had made complaints about Green on Homes North forms.
Mr Bouveng said she had motivation to do so in an effort to transfer rentals and she did not "substantiate" the claims.
He submitted Justice Stephen Campbell should "place very little weight" on them when considering if there were issues between the former neighbours.
Mr Bouveng told the court the accused had never made admissions to the murder.
Defence will continue closing on Wednesday.
