ROGER Rogerson, convicted yesterday of the murder of Jamie Gao, is officially Australia’s first serial killer with a badge. The cold-blooded killer is linked to nearly a dozen unsolved murders.

After six-and-a-half days of deliberation, the jury delivered their verdicts — guilty for both Rogerson and co-accused Glen McNamara on charges of murder and taking part in the supply of 2.78kg of ice.

But the student drug dealer Gao is just the tip of the iceberg.

Roger Rogerson has killed four people that the police and public know of — but there are many more, including two women, that he has been linked to.

It can also be revealed for the first time that police believed Rogerson was going after the Police Commissioner Tony Lauer and Superintendent Clive Small in 1990 because of their pursuit of him over the attempted murder of undercover officer Michael Drury in 1984.

Rogerson was acquitted of conspiring to kill Drury in 1989.

Drury has revealed for the first time that there was another plot to have him killed.

Within days of his arrest for the murder of Jamie Gao, the NSW Police Integrity Unit approached his legal advisers to see if Rogerson would give up the secrets of Sydney’s underworld and possibly even do a deal.

Likewise, Western Australian police said they wanted to talk to Rogerson over suspicions he had information about the murder of a prostitute in 1974.

Neither organisation have spoken to him yet.

The Telegraph has also uncovered that the file of a Sydney woman who disappeared before giving evidence about Rogerson has vanished

Homicide detectives as recently as three years ago questioned Neddy Smith over accusations he knew who killed the 31-year-old and buried her on beach between Sydney and Wollongong.

The file relating to an inquest held in 2001 into her disappearance is missing from the coroner’s office.

Rogerson was caught by a senior legal officer in the early 80s in the coroner’s office early one morning going through documents.

A Daily Telegraph investigation into the life and killings of Roger Rogerson has uncovered a number of deaths linked to him and his links to various crimes in Australia.

You name it and Rogerson was up to his ears in it.
