THE mother of Tyrell Cobb has pleaded guilty to manslaughter this afternoon and it has been revealed she allegedly delivered the blow that killed the four-year-old.
Heidi Strbak appeared in the Supreme Court in Brisbane this afternoon supported by family and friends just weeks after the case made headlines when her ex-boyfriend received a paltry four-year sentence on the same charge.
Tyrell was found unconscious inside a Gold Coast home on May 24, 2009, and taken to hospital, where he was pronounced dead.
Police allege he died from a blunt-force trauma injury to his abdomen and had sustained about 70 injures over a period of time.
Strbak and her then-partner Matthew Scown were initially charged with murder, but the charges were downgraded at a committal hearing last year.
Crown prosecutor Phil McCarthy said it would be alleged Strbak was “the author of the blunt-force trauma” that killed Tyrell.
Her barrister said the sentence later this month would be contested as she was pleading guilty on the basis of criminal negligence.
