An aspiring beautician’s animosity towards her ex landed her behind bars after she committed a vicious home invasion.
Tegan Lee Martin, 24, was drunk and high when she used a taser on her ex-boyfriend in the “pre-mediated” attack.
During sentencing, the District Court heard Martin had previously been in a relationship with the victim, Jacob Tiller, for approximately five years.
“Your relationship was characterised by dysfunction and immaturity on both sides,” Justice Julie McIntyre said.
The court heard the relationship ended three years prior to the offending but there was still some “ill will” between the pair.
Martin, who was under the influence of drugs and alcohol, rushed through Mr Tiller’s unlocked sliding door on October 6, 2021 in Port Lincoln.
Martin opened the bathroom door where Mr Tiller was and Martin used a taser on him, while her co-accused is alleged to have hit him on the elbow with a metal pole.
Mr Tiller pushed past the duo and attempted to run to the back door but fell to the ground.
“(Your co-accused allegedly) stabbed Mr Tiller with the knife to the side of the head. You continued to use the taser on Mr Tiller,” Justice McIntyre said.
Mr Tiller was taken to the Port Lincoln Hospital with an 8cm laceration to the side of his head.
The cut extended through the skin, muscle and onto the bone and required emergency surgery and 10 stitches.
Martin, of Port Lincoln, pleaded guilty to serious criminal trespass and causing harm with intent.
Justice McIntyre said the victim now suffered from post-traumatic stress disorder and no longer feels safe in his own home.
“Mr Tiller says he has also developed a short-term memory loss and has continuing head pain due to his injury,” she said.
The court heard Martin was addicted to marijuana, MDMA and alcohol but hadn’t taken drugs or alcohol since her arrest.
The court heard Martin was currently employed as a cleaner but had aspirations to complete further beauty training.
Justice McIntyre said she accepted Martin was remorseful for her actions and her time in custody was a catalyst for turning her life around.
“This was a violent, premeditated home invasion … you were an active participant in the assault upon Mr Tiller,” she said.
“The fact that you were, at the time, under the influence of drugs and alcohol does not excuse your appalling behaviour in any way.
“Your motivation is obscure, but has its origins in what was described as your toxic relationship with Mr Tiller. Again, this is no excuse.”
Justice McIntyre sentenced Martin to two years and five months jail, with a non-parole period of 10 months.
