A Brisbane woman accused of deliberately mowing down her husband and another woman after discovering they were having an affair had allegedly tracked his phone to find their meeting place, a jury has heard.
In the District Court on Monday, Christie Lee Kennedy pleaded not guilty to unlawfully striking David Larkin and Zowie Noring and causing them grievous bodily harm in March last year.
During opening submissions, the court heard Mr Larkin and Ms Noring had not long met up near a Wavell Heights park when Mrs Kennedy hit them with her SUV.
The court heard directly after colliding with the pair, the 37-year-old got out of the car and continued to attack Ms Noring, grabbing her by the hair before repeatedly punching her in the back of the head.
Although Mrs Kennedy denied intentionally running them over, she has admitted to the later attack pleading guilty to unlawful assault.
The court heard Mr Larkin and Ms Noring had met six years prior and had only remained acquaintances until a few months before the alleged offences.
Giving evidence in person, Mr Larkin told the court the two "became closer" in early 2021 and had been a "support for each other".
"We were both talking about our trauma," he said.
"I had a lot on my mind, I wasn't coping with things that well and just needed someone to talk to."
Mr Larkin described his marriage as being "fairly rocky" and had initially denied being in a sexual relationship with Ms Noring, but under cross examination conceded he had been cheating on his wife at the time.
"We had met once and been intimate … We were having an affair if that's how you want to describe it," he said.
'Tracking app' installed on Larkin's phone
The court heard a week before the alleged offences, Mrs Kennedy with permission installed an application on her husband's phone that could pinpoint his location, but she told him it was to "organise bills and invoices".
On the day of the alleged offences, police had found the same application had been activated on Mrs Kennedy's phone, allowing her to see where he was.
Crown prosecutor Jennifer O'Brien told the court Mrs Kennedy allegedly tracked her husband to the park, before using a "large and powerful weapon" in an "extremely dangerous" and deliberate manner to injure him and Ms Noring.
"The car was still moving when she hit them as well, there was no attempt to swerve away or correct the course," she said.
Mrs Kennedy's defence lawyer Penny White told the court on the day of the alleged offences her client's "world came crashing down".
"She found herself in a position no-one else would want to be in," she said.
"She's found out that her husband of nine years, her partner of 15 years, the father of her two young children was having an affair with another woman."
"The events that followed from that realisation … all happened in a matter of seconds after she found that out."
Mrs White told the court Mrs Kennedy was not contesting that she had run into the pair and urged the jury to consider all the evidence carefully.
"What is in issue is the allegation that Christie Kennedy intended to hit the two complainants and that she intended to disable them by her actions that day," she said.
The trial before Judge Tony Moynihan continues.
