As the police taskforce investigating the mystery of the severed head found on Rottnest Island continues its inquiries, it is now believed the victim was a player in a major WA crime syndicate.
Stephen Ramon Cookson was due to stand trial later this year on serious allegations of drug trafficking.
His severed head was found by an 11-year-old girl while beachcombing in Porpoise Bay on January 6.
Police allege Mr Cookson was a player in a major drug cartel involved in the importation of high grade methamphetamine from New South Wales.
He was one of five people arrested during raids by organised crime detectives on properties in South Perth and Burswood in September 2010.
There police seized around 1.25 kgs of high purity methamphetamine.
The highly covert police operation involved months of intelligence gathered through phone intercepts and police surveillance both in Perth and New South Wales.
Police allege Cookson was the principal of the methamphetamine once it reached WA and it is also alleged he organised collection of money to fund the purchase of the drugs.
He and three co-accused were due to stand trial on charges of possessing methamphetamine in the district court in April.
It is understood Cookson had several outstanding debts in Victoria.
