In January 2020, Meliame Fisi'ihoi was watching TV in the sitting room in the early hours of the morning, when she got up to check a noise she heard outside her Favona home, a court has heard.
The mother of six went to the window, raised her right hand and opened the curtain.
As she looked out, a gunshot was fired from close range, killing Fisi'ihoi instantly.
The court heard the 57-year-old woman's husband and younger children were home in bed at the time.
The Crown says the bullet was meant for Fisi'ihoi's eldest son after a botched gun deal.
