The Sunday Mail today reveals the fugitive's face in a bid to help track him down as sources claim he is living the high-life in a millionaire's playground in Spain.
Sources say Ferguson was smuggled out of the country by a gangland tycoon from Calton, in Glasgow.
He been hiding out in Puerto Banus on the Costa Del Sol where he has stayed one step ahead of Scottish detectives despite a warrant being issues for his arrest.
Meanwhile, the families of the victims in the double murder being probed by detectives hunting Ferguson are sti ll waiting for justice.
Tam was shot in the chest in the car park of the Auchinairn Tavern in Bishopbriggs in June 2007.
Bates - who was also a suspect in Tam's killing - was discovered dead in an oil drum weeks later.
A European arrest warrant was issued for Ferguson later that year and Strathclyde Police have insisted his face cannot be revealed ever since.
David Whitton, Labour MSP for Bishopbriggs, where the first murder took place, said "It is absolutely right that the public are given the opportunity to recognise this man and would like to know exactly what is being done to execute his arrest warrant.
"I remember meeting Tam Cameron while canvassing and his shocking death had ter r ible ramifications.
"In the interests of justice, everything possible must be done to bring this man back to Scotland."
Labour justice spokesman Richard Baker said: "Derek Ferguson has apparently chosen to leave Scotland and has avoided questioning for four years.
"It is right to highlight this man and questions must be asked why he has evaded police questioning for so long."
Tory justice spokesman John Lamont said: "This is a man who has evaded justice for four years and it's important that he is caught as soon as possible.
"Revealing his face will surely help in that process and it's certainly in the public interest for the public to know what he looks like."
Tam Cameron's family have so far refused to comment about the case.
But a gangland source said: "It has surprised people that Ferguson has not been caught by now.
"People were expecting to see him back in months but years have passed.
"He seems to have been forgotten about."
It is believed Tam was murdered after discovering a member of his family had been bullied into helping commit a bank fraud.
Detectives wanted to question Bates and Ferguson, both from Possil in Glasgow, over his death.
Bates's decomposed corpse was found crammed in a drum in the River Clyde, near the Erskine Bridge.
He had suffered a brutal and sustained attack two weeks before.
Convicted heroin dealer Bates's family only managed to identify him when police showed them photos of two gold rings he was wearing.
He had just been released from prison and had been earning money as an enforcer.
Strathclyde Police suspect he was killed because he wanted to hand himself in for questioning. The force yesterday declined to comment.
Tam's murder came just 18 months after his son Ross, 20, died after being stabbed at a party.
Andrew Burns attacked Ross in the early hours of New Year's Day 2006 and was convicted of culpable homicide at the High Court in Edinburgh.
He was jailed for nine years.:Text may be subject to copyright.This blog does not claim copyright to any such text. Copyright remains with the original copyright holder.
