A man allegedly shot a woman in the the chest and dumped her at a Melbourne hospital after she tried to break up with him.
Qasim House is charged with the murder of 40-year-old Yen Ngo at Sunshine North on November 23, 2017.
Three days before Ms Ngo died, she told House their relationship was over, prosecutors told a Victorian Supreme Court jury this week.
"I love you but I'm sorry, I can't be with you," the woman is said to have texted House.
"I really love you but I don't think we're going to work."
House allegedly responded with a barrage of messages including "you've pushed it too far this time. You're a backstabbing traitor".
"Are you really ready for me to be nasty? This is my turning point," the then 32-year-old allegedly wrote.
The day Ms Ngo died, the court was told one of her flatmates found House sitting at the end of the woman's bed as she slept.
Hours later Ms Ngo's landlord, who also lived at the property, heard House yell "help me, help me, help me," and went upstairs to find the man trying to move Ms Ngo's blood-covered body.
House drove her to Sunshine Hospital before fleeing, crashing twice and stealing another car as he tried to avoid police, the court was told.
After being arrested with a sawn-off shotgun snapped in two, House is said to have told officers the shooting was an accident.
"She struggled with me. She picked up the gun and goes, 'kill me, kill me, kill me'," the court was told House said.
"I grabbed the top of it, went to pull it towards me - bang. She ripped it back, bang, and it got her."
House's lawyer says his client loved Ms Ngo and the gun went off as he tried to wrench it away from her because he feared she was going to kill herself.
The trial is expected to continue on Monday.
