A man who allegedly shot dead a woman at a home in Sunshine North has been charged with one count of murder.
Police charged Nelson Lai, 34, of Sunshine North, at an out-of-sessions court hearing in Melbourne.
He was remanded to appear at the Melbourne Magistrates' Court on Monday.
Paramedics were called to a house on Meadowbank Drive in Sunshine North about 9am (AEDT) on Friday to treat a woman for upper body wounds, but were unable to enter until police declared the scene safe.
By the time they reached her in a rear bedroom of the home, the woman had died.
Detective Senior Sergeant Stephen McIntyre said the Sunshine North man, who is known to police, is believed to have known the woman but the extent of their relationship is yet to be determined.
Det Sen Sgt McIntyre said police were in possession of a firearm.
Police have not revealed how many shots had been fired or how many wounds the woman, who is yet to be identified, sustained.
He said he was unsure how long paramedics had to wait before they were able to enter the house.
"The scene had to be made safe prior to their entry," Det Sen Sgt McIntyre said.
"Given the fact that there was a firearm involved in this incident they obviously had to wait for police to attend."
In a bizarre twist, the bodies of two women, one elderly and one middle-aged, were found in a house in the same street soon after the shooting, but their deaths are not being treated as suspicious.Police said their deaths were unrelated to the shooting.
