According to prosecutor Sean Stocks, the child and his family pursued Slater and his relatives near a Perth railway station after Australia Day celebrations last year. The court heard that the two families clashed several times throughout the night, before Slater received a deadly wound to his chest.
The report alleges that the victim was stabbed, puncturing lungs and aorta to puncture.
While CCTV footage didn’t capture the murder, The Australian reported that Stocks claimed footage did show the child holding a screwdriver less than a minute later. It was covered in the victim’s blood.

The court also heard how CCTV footage captured the child reaching into a vomit-filled bin to search for a weapon so he could be part of the group attack.
While the child has pleaded guilty to manslaughter, the state has pursued a murder charge.
