Woman jailed after trying to kill ex husband with car

A WOMAN "lost the plot" when she drove past her ex-husband carrying groceries into his new flame's home while her children were going without.

With the scene of a "happy family" in front of her, Wimon Seijbel-Chocmingkwan drove straight over the Redbank Plains front yard and at her ex-husband.

Seijbel-Chocmingkwan then went for her ex-husband's girlfriend with a knife.

The 43-year-old's actions gained her a 10-year jail term.

Seijbel-Chocmingkwan pleaded guilty in the Brisbane Supreme Court on Monday to attempted murder and dangerous operation of a vehicle.

Crown Prosecutor Glen Cash said Seijbel-Chocmingkwan yelled "I will kill you" as she drove across the Argyle St property on November, 5, 2010.

He said her former husband sustained minor bruising after Seijbel-Chocmingkwan struck him with her car.

But the former husband's new partner sustained a serious injury after Seijbel-Chocmingkwan went at her with a knife will screaming "I'll kill you, I'll kill you, I'll kill both of you", the court heard.

The commotion only ended when a neighbour intervened and restrained Seijbel-Chocmingkwan until police arrived.

Seijbel-Chocmingkwan grabbed a pen and stabbed herself in the chest when emergency services arrived.

Defence barrister Steve Kissick explained his client had driven past the Redbank Plains home and saw a happy family.

"She said it upset her greatly," Mr Kissick said.

"...he was paying for family while her children were doing without.

"She then lost the plot."

The court heard Seijbel-Chocmingkwan may have suffered from a major depressive episode.

Justice David Jackson sentenced her to 10 years jail and declared the crime a serious violent offence, which means Seijbel-Chocmingkwan will have to serve 80% of her jail term.
