Hundreds of mourners have held a candlelight vigil for stabbing victim Prabha Arun Kumar, four days after she was murdered in a western Sydney park.
The 41-year-old Indian national was talking on her mobile phone to her husband, who lives in India with their 10-year-old daughter, when she was stalked and then stabbed in the neck on Saturday night.
More than 300 people have retraced Mrs Kumar's final steps in Parramatta Park, just weeks before she was to be reunited with her family in India.
Friends, work colleagues and strangers braved the rain and lightning on Wednesday night to chant prayers and add their bouquets, incense and candles to the memorial site where Mrs Kumar's body was found, 300m from her home.
Her close friend, who did not wish to be named, said Mrs Kumar used to gather gifts to send to her daughter Meghana to make up for her absence as she worked to support the family.
"She has collected bracelets, fancy footwear, jewellery. She didn't want Meghana to miss her," the friend told AAP.
Mrs Kumar had been working for IT firm Mindtree since 2012, but was planning to return to India in April.
Parramatta Superintendent Wayne Cox assured the community that police would not "leave a stone unturned" to find Mrs Kumar's killer.
"I'm here to reaffirm our commitment and passion," he told those gathered as he laid a bouquet.
The victim's husband, Arun Kumar, arrived in Australia on Monday morning to the news his wife had died.
"She was walking while talking to Arun (her husband) on the phone when she said that a suspicious-looking man was following her," Mrs Kumar's brother-in-law, Thrijesh Jayachandra, told The Hindu newspaper.
"The next moment he heard her scream for help and then plead with the man not to harm (her) and take all her belongings if he wanted.
"Seconds later, he heard her scream and say she was stabbed."
It's believed Mr Kumar will make a public plea for information to help find his wife's killer.
