Stacey Taylor hadn't heard "a single word" from the father of her unborn child for more than six months when he targeted her western Sydney home during a terrifying shooting spree.
Within an hour, the gunman identified as bodybuilder Daniel King would be killed in a shootout with police, after opening fire on his former lover's home and two police stations with a 12-gauge shotgun.
One officer was taken to hospital with non life-threatening wounds following King's final confrontation at Penrith Police Station on Wednesday night.
King's shooting rampage began when he opened fire at the Marayong home of Ms Taylor, who is seven months pregnant.
A "scared" Ms Taylor told Ten News she was in bed with her children about 8.45pm when she heard a massive bang, followed by another.
She looked out her window and saw King at the bottom of her driveway, shooting towards the house on Quakers Road.
"He wasn't very happy about me being pregnant and that's where all this fuss started from," she told Ten News.
"When I found out I was pregnant I had threats for about three weeks."
Ms Taylor told reporters 32-year-old King had claimed the baby wasn't his, and wanted DNA testing and an abortion.
"If I didn't, he was going to kill himself," she said King had claimed.
King had also threatened to hire a hit man "to bash me and stab me in the stomach to make me lose my baby so I wasn't pregnant any more", she said.
They had known each other in primary school, reconnected and had a couple of dates but "the person I knew was not somebody who would do something like this".
"(I was) very frightened not only for myself but mainly for my children and my family," she said.
After leaving Ms Taylor's home on Wednesday, police say King fired into St Marys Police Station about 9.15pm before driving to the Penrith station where he shot at officers outside.
Deputy Commissioner Jeff Loy said they had "no choice" but to return fire.
King died at the scene.
Officers involved in the shootout were shaken, but had also "reflected on their own families and themselves and how fortunate they were not to be killed".
"For police to be confronted and to stand up in a confrontation under fire, has shown extreme courage," Deputy Commissioner Loy told 2GB.
A male constable suffered pellet wounds to the back of the head and was taken to Westmead Hospital with non life-threatening injuries, police said.
Several other officers suffered minor injuries that were not gunshot-related.
Deputy Commissioner Loy said it wasn't yet clear if he was a licensed shooter, but his gun was the sort used by tactical police.
Witness footage posted online showed him falling to the ground after being shot multiple times.
The woman filming the footage from a nearby building can be heard screaming "Oh my God! Oh my God! Oh my God!" as the shots ring out.
Mick Lumtin, who was hosting a trivia night at a nearby pub, said police asked the man to put down his weapon before "there was just a ray of shots going out".
"I don't know, maybe 14 or 15 shots, pretty loud," he told the Seven Network.
Local resident Roy told Nine News he heard the sound of gunfire.
"I heard three loud bangs. It sounded like it was firecrackers," he said.
A critical incident investigation team from the homicide squad will investigate the incident, and the investigation will be independently reviewed.
