Woman carved name into ex-partner’s back before slashing his wrists, court told
A woman carved her name into her ex-partner’s back, drawing blood, just before slashing his wrists and convincing him he attempted suicide, a court has been told.
Details of Theresa Ann Coss’ offending were revealed at Brisbane Supreme Court on Tuesday as she learned her fate for two “motiveless and inexplicable” attacks on two different men within months of each other.
The court was told Coss had significant mental health issues that were exacerbated by her use of drugs.
She pleaded guilty to one count each of malicious act with intent and wounding.
The court was told Coss and her ex-partner had been drinking at New Year’s Eve celebrations in 2019 before they went home.
Crown prosecutor David Meredith said Coss followed the man to the bedroom, tying his feet with a belt and squirting baby oil on his chest.
“He didn’t complain, he accepted this,” Mr Meredith said.
Coss scratched her name onto his back with a sharp instrument “causing it to bleed”.
She then slit the man’s wrists, causing him to pass out.
When he regained consciousness she claimed he attempted to commit suicide and she “saved” his life.
Months later, she attacked a 47-year-old man at a caravan park in Nambour after inviting him over to watch AFL on March 28, 2019.
Mr Meredith said she began repeatedly stabbing the man with a large kitchen knife as they wrestled to the ground.
After the scuffle subsided, Coss retrieved a butcher’s knife from the kitchen and began striking the victim in the arms and head.
The victim suffered multiple incision wounds to his head, shoulders, back and thigh and collapsed weak from blood loss.
During the altercation Mr Meredith said Coss told the man he was going to die and was “going to another world”.
As he cried for help she told him: “No one’s going to hear you”.
Coss then locked the man inside, turned on a gas stove and placed two phones in the microwave to start a fire.
The victim was rescued by neighbours after banging on the window.
Mr Meredith said Coss was confronted while attempting to leave the park but denied committing the offences.
The court was told Coss had a “significant” history of trauma and mental health issues but now had support plans with the help of mental health doctors.
Data has revealed over 220,000 Australian children are medicated with antidepressants and other prescription drugs as a result of mental health issues.
Defence barrister Laura Reece said her client had experienced a tragic personal loss which caused a “spiralling” in her life and set in “long instability”.
“There is an underlying psychiatric illness, she remains quite heavily medicated in custody,” Ms Reece said.
Ms Reece said at the time of the March 28 stabbing, Coss had been using drugs heavily and had not slept in days.
She said her client had been working while in custody and had restored her relationship with her daughters.
The court was told Coss had been productive in custody and had completed white and blue card qualifications.
“The blue card enables her to be on the list for a parenting course in custody, with a view to care for the children in the mothers and babies unit,” Ms Reece said.
“She appears to be very engaged with that unit already.”
Justice David Boddice sentenced her to eight years’ jail with a parole eligibility date fixed today.
