West Australian police have charged a 28-year-old man with murdering convicted drug trafficker Stephen Cookson, whose head was found in a bag on Rottnest Island, off Perth.
Detectives arrested, questioned and released a man on Wednesday night, after a forensic team scoured a property near Mandurah while continuing the search for the rest of Cookson's body.
Last night they charged the 28 year-old from Guildford with one count of murder.
He is due to appear in court today.
