But the police investigation has been rocked by the suicide of an an accomplice who became a rollover witness in the alleged bribery scandal.
Grant Alexander – described by the Corruption and Crime Commission as “the fixer” in the bribery affair – died in New Zealand this week.
Three executives from North Metropolitan Health Service were allegedly getting kickbacks in return for lucrative government contracts given to building and maintenance firms.
Two of those senior bureaucrats –John Fullerton and David Mulligan – have been charged by police.
Mr Fullerton is facing 47 counts of acting corruptly as a public official and gaining benefits by fraud.
Mr Mulligan is facing 10 charges.
Mr Alexander had become a rollover witness for the police and was due to fly into Perth and surrender his passport.
Detectives had taken detailed statements from Mr Alexander, who was working in London when the bombshell CCC report was tabled in Parliament.
It’s unclear how his suicide in New Zealand, Mr Alexander’s birthplace, might affect the ongoing police investigation.
According to the damning 2018 CCC report, the three executives took money, travel, accommodation and other hospitality in return for awarding lucrative contracts.
Both Mr Fullerton and Mr Mulligan will appear in court on March 25th.
