A teenage boy has pleaded guilty to the manslaughter of a pregnant mother, after he fatally hit her in the head with a piece of concrete.

A teenage boy has pleaded guilty to a downgraded charge of manslaughter after fatally hitting a pregnant woman in the head with a piece of concrete.

The 17-year-old appeared in Perth Children’s Court on Wednesday over the incident on November 29, where police allege he hit Diane Miller in the head with a piece of concrete as she sat in her car in the carpark of Karawara’s Waterford Plaza, just south of Perth’s CBD.

Ms Miller, 30, died in hospital from her injuries three days later.

She was five months pregnant at the time, and lost her unborn child.

A boy has pleaded guilty to a downgraded charge of manslaughter after fatally hitting a pregnant woman in the head with a piece of concrete.

Diane Miller was hit in the head with a slab of concrete as she sat in her car in the carpark of Karawara’s Waterford Plaza, just south of Perth’s CBD.

The 17-year-old was initially charged with grievous bodily harm, but that was upgraded to murder following Ms Miller’s death.

The charge was then discontinued at the boy’s court appearance on Wednesday, with prosecutors accepting his guilty plea to the lesser charge of manslaughter.

Ms Miller, 30, died in hospital from her injuries three days later. She was also five months pregnant at the time, and lost her unborn child.

The court was told the boy, who can’t be identified, was diagnosed with foetal alcohol spectrum disorder in 2020.

He’ll face a two-day sentencing hearing from April 27.

He cannot be held legally responsible for the death of Ms Miller’s unborn child.
