A man accused of raping and murdering a Melbourne woman more than 30 years ago used to live with her, a court has been told.
Meth Mean has been charged with the cold case rape and murder of 27-year-old Ranny Yun, whose body was found at her Springvale home on October 15, 1987.
Mean on Monday faced the first day of a committal hearing at Melbourne Magistrates Court to determine if he stands trial.
The first witness Heng Tang said Ms Yun used to hold gambling events at her home before she was murdered.
He also said Ms Yun had told his wife about an incident at her home.
"She said that when she had a shower, someone sneaked in and looked at her," Mr Tang said via video link.
Mr Tang said Ms Yun seemed to think it was a relative who spied on her.
The retiree also said he never noticed any arguments or incidents linked to the gambling events Ms Yun organised, which generally consisted of card games and small $1 bets.
Mean's mother, Chreach Tep, said Ms Yun lived at their family home at Springvale not long after the younger woman arrived in Australia from Cambodia via a refugee camp in Malaysia.
But she later moved out and lived nearby with her husband.
Ms Tep said Mean's younger brother found Ms Yun's body when he went to her home for help with homework.
"He saw blood and just ran back home," she said through a Khmer interpreter.
"When he came back home he called out for his dad and said 'papa, sister-in-law died'."
Ms Tep said her sons and husband spoke to Ms Yun as if she was a member of the family.
"They were communicating with each other in a normal way, like a family member (would)."
"Did you ever see any arguments or fighting between Ranny and Meth?" defence barrister David Sexton asked.
"No," Ms Tep replied.
The hearing before magistrate Donna Bakos continues.
