The son of the prime suspect believed to have murdered missing woman Sharron Phillips has given chilling testimony his father was Australia's "gingerbread man" who would never be caught.
An emotional Ian Seeley fought back tears as he exposed his father as a "mass murderer" who made a deathbed confession begging him to "give the girls back" days before he died in 2002.
Queensland's state coroner reopened the inquest into the 1986 disappearance of Ms Phillips after taxi driver Raymond Peter Mulvihill was unveiled as the number one suspect by police.
Ms Phillips, 20, vanished on May 8, 1986, while waiting for her boyfriend after running out of petrol in Wacol, in southwest Brisbane.
Mulvihill drove a cab that was based at Wacol, and his son said Ms Phillips was a victim in the wrong place at the wrong time.
"For him, for my father, it was quick, easy and simple. It was one of the simplest jobs he has ever done," Mr Seeley told the court on Wednesday.
"Everything lined up that day. It was not premeditated. He did not stalk her. She approached him."
When asked how Ms Phillips died, Mr Seeley said: "He strangled her. He strangled all of them."
On the night Ms Phillips vanished, Mr Seeley arrived at the taxi base to pick up his father when Mulvihill jumped out to stop him saying: "I've got something I have to put into the car".
Mulvihill ordered his son to "wait out the front" before reversing the car around the back of the base himself.
Mr Seeley told the court he waited by a phone box -- the same one Ms Phillips had used to call for help.
A short time later, a police patrol arrived, demanding to know what he was doing there.
"I told them it was none of their business. This is harassment and told them to piss off."
While police were talking to him, Mr Seeley heard his father mutter, "get the f*** in there, or I will kill you", followed by the sound of two car boots closing.
He said the officers were probably "only 20 metres away" and asked him what the noise was.
"I don't know. Why don't you go have a look?" Mr Seeley told the police.
The officers failed to investigate.
It was on the drive home Mr Seeley began to suspect someone could be in the boot.
"I heard a bang, and I said to my father: 'What the f*** have you got me into?'.
"I did not know there was a woman in the boot .... but I began to suspect."
When the pair arrived home, Mr Seeley claimed his father held a knife to his throat, cut him under the chin before ordering him from the car, and driving off alone.
"I'm sorry. I gave up. I surrendered. I was a coward," Mr Seeley said.
"I'm not asking for anyone's sympathy, but it was just f***ed. The guy's a mass murderer."
Days after Ms Phillips went missing, Mr Seeley claimed his father scoffed at media reports saying: "You can say what you like, but they won't catch me. I'm the gingerbread man."
More than 30 years later, Mr Seeley claimed Mulvihill made a dying declaration to killing "lots" of women when he asked him to "give the girls back".
"I asked him where are these girls, and he said in the drain where I said Sharron was."
Mr Seeley gave the location to police, prompting an unsuccessful search of council-owned industrial land at Carole Park in 2017.
Under questioning, Mr Seeley admitted a history of mental illness and previously being diagnosed as suffering from "grandiosity".
He was accused of fabricating the story to match a podcast he has recently been involved in.
"Your evidence has been made up to support the story you have created for your podcast," he was asked.
Coroner Terry Ryan directed court recordings were not permitted for use in the podcast.
The inquest continues.
