The son of the key suspect in the disappearance of Sharron Phillips believes his father was a mass murderer, saying he "strangled all his victims".
Talking at the inquest into Ms Phillips' 1986 disappearance in Brisbane yesterday, Ian Seeley claimed his father Raymond Mulvihill "strangled her".
"He told you?" the counsel assisting the coroner asked.
"He strangled all of his victims," Mr Seeley replied.

Recounting the night Ms Phillips, then 20, went missing, Mr Seeley told the coroner he ended up at Station Road, after spotting his father drunk and driving his taxi.
"He just jumped up in front of me with both hands up. I said 'jump in,'" Mr Seeley claimed.
"He said 'no, back it up, back it up, I've got to put something in the car.'''
Mr Seeley said at the inquest that police turned up moments later - the same officers he claims had just half an hour earlier pulled him over for a broken taillight.
"While they were there, I heard both boots close," Mr Seeley told the court for the first time.
He said it was followed by Mr Mulvihill saying, "f------ get in there, or I'll kill you."
Mr Seeley told the court the officers didn't investigate further and left the father and son - a claim that counsel representing Sergeant Stephen Jones refuted.
"I suggest to you that did not occur, no police officer would ignore that," the counsel claimed.
Mr Seeley stated that his father forced him to drive at knifepoint before hearing a bang from the car's boot.
"'What the f--- have you got me into?' I knew there was something bad. I didn't know there was a woman in the boot," Mr Seeley said.
The court also heard Mr Seeley went to the Oxley police station just two days after Ms Phillips disappeared to prove he'd fixed his broken taillight, but claimed police didn't want to know whether he suspected his father was involved.
Mr Seeley further told the court that Mr Mulvihill confronted him at home, telling him, "You can say what you like, but they won't catch me, I'm the gingerbread man", and that Ms Phillips had hit him with a tyre iron.
"She hit him in the head. Sharron pulled the tyre iron and hit him," Mr Seeley claimed.
In 2002, Mr Mulvihill made a deathbed confession, urging Mr Seeley to go to police and to "give the girls back" that were "in that drain" with Ms Phillips.
The coroner will give his findings at a later date.
