Michael James Quinn became a quadriplegic after allegedly fatally stabbing his on-off girlfriend of around three years, Cherie Vize, and turning a knife on himself at the Wollongong home in NSW he shared with his family in July 2013.
His neighbour Sheree Broad on Wednesday told a judge-alone trial she went into the family’s yard where Ms Vize was bleeding, struggling to breathe and being held up by Quinn’s mother, Joanne.
She said she looked up to see Quinn, who has pleaded not guilty to murder, standing on the verandah with his brother.
‘As he walked down the stairs, did you see something?’ crown prosecutor Mark Hobart SC asked her in the NSW Supreme Court.
‘I saw a knife stuck out of his stomach,’ Ms Broad said via audio visual link.
The Crown alleges Quinn was an ‘extremely jealous’ person who had recently found out Ms Vize was seeing a new lover.
They say he meant to cause her at least grievous bodily harm after reading her text messages, including one where Ms Vize talked about the morning after pill and ‘the things we do for sex’.
Quinn’s brother Thomas Quinn gave evidence that he shouted as loud as he possibly could as Michael started to stab himself.
He said his brother’s face was blank and that he showed no reaction before collapsing in the yard.
‘Why have you done this, what has gone wrong?’ the court heard Thomas Quinn asked the accused murderer.
The defence says Ms Vize was accidentally stabbed during a struggle and that Quinn, who was on medication for obsessive compulsive disorder, was not of normal mind when the incident occurred.
Thomas Quinn told the court he had seen his brother run a razor blade across his face in the years before the fatal stabbing.
He also said Michael had injured himself from obsessive scrubbing and had repetitive behaviours involving locking doors and flicking light switches.
The court has previously heard Quinn asked a police officer to shoot him and said ‘I can’t believe I missed my heart’ when emergency services arrived.
Ms Broad ran away back to her house after seeing the knife lodged in Quinn.
The brothers had recently found out their grandfather, with whom they were extremely close, was not expected to live, the court heard.
Justice Robert Beech Jones has the option of finding Quinn guilty of manslaughter.
