THE then-girlfriend of a 25-year-old man accused of killing Caine Hammond, 28, at a property in Euleilah in 2012 has given evidence on day four of the trial in the Bundaberg Supreme Court.
Lucas John Scot Bell pleaded not guilty to causing the death of Mr Hammond, who died in a Brisbane Hospital two days after he sustained a serious head injury.
Bell's girlfriend at the time, Tori Hutchinson told the court Bell pushed Mr Hammond twice in the kitchen area and the second push sent Mr Hammond into the oven and onto the floor.
She said Mr Hammond's back had made contact with the oven but that he did not hit his head in that instance and managed to get back onto his feet and regain his balance.
Miss Hutchinson said Mr Hammond then turned around and in doing so, lost his footing and fell, hitting his head on all three levels of the kitchen bench.
"He got back up, turned around and lost his balance and fell and hit his head," she said.
"He hit his head on every shelf - the back of his head - every single one of the three shelves."
Miss Hutchinson said the fall left Mr Hammond lying on the floor, flat on his back.
"He was unconscious, he looked dead," she sad.
"He wasn't responding to any of us talking to him.
"His eyes kept rolling back into his head."
Miss Hutchinson said Bell then tried to punch Mr Hammond as he lay on the ground but Bell's father and another person at the house held him back.
"He (Bell) was trying to throw punches at Caine, none of them connected but," she said.
Neuropathologist Thomas Robertson performed the autopsy of Mr Hammond's brain tissue and gave evidence about the injury which resulted in Mr Hammond's death.
When asked by crown prosecutor Greg Cummings if it was possible hitting a kitchen bench in such a way as Miss Hutchinson described would have caused the injury, Dr Robertson said it was "less likely".
Dr Robertson said it was more likely he had hit the floor directly because of the significant amount of force required to cause such an injury.
The court was also read a statement from Bell's mother Michelle Bell in which she said she suffered from bipolar disorder and short-term memory loss and had limited memory of the night in question.
