A Dunedin teenager who bludgeoned his mother to death with a dumbbell reported the murder to police after a 4km walk.
The defendant — who turned 18 shortly before the incident — appeared in the High Court at Dunedin yesterday, where the details of his attack were outlined.
On January 13 this year, he was celebrating his birthday at home with a friend and his mother.
Shortly before midnight, the associate left the two alone.
According to court documents, at 1.15am, the defendant picked up a 10kg dumbbell and repeatedly slammed it into his mother’s head as she lay in bed.
An autopsy two days later found 15 separate lacerations and extensive facial fractures.
Before leaving the address, the teen placed towels on the stove and turned it on.
As it smouldered, he packed a bag with underwear, a T-shirt, shorts and a bottle of water and fled on foot.
In Fea St, North Dunedin (4km away), the defendant knocked on a door and asked the residents if he could use a phone.
The court heard he spent 26 minutes on the call to police, at first describing "an assault" and reluctant to give detail.
"During that phone call, the defendant sounded lucid and coherent, but at some stages sounded upset and crying," a summary of facts said.
He provided his name and his home address, where the killing had taken place.
When asked whether an ambulance was needed for the victim he said no, police should "just go in".
His mother was dead, he confirmed.
The defendant was asked how serious the assault had been.
"Very," he replied.
What type of assault had he committed?
"A murder," he said.
When officers entered the home they found the fire alarm sounding, a haze of smoke in the kitchen and the victim dead in her bed.
The murder weapon was on the floor of the hallway.
Half an hour later, the defendant was picked up in Fea St, where he had been waiting in his blood-stained clothing.
The teenager, who appeared in court wearing a bright-orange prison-issue tracksuit, was remanded in custody and will be sentenced in August.
Name suppression continues until that date.
