'I lived with a murderer', son of Sharron Phillips' killer says

The son of a deceased taxi driver police have identified as the killer of Ipswich woman Sharron Phillips has told of how he became an unwilling accomplice to his father's crime.


Police on Friday revealed Raymond Peter Mulvihill murdered the 20-year-old after she approached him for a lift home on the night of May 9, 1986.

He drove a cab based at the back of a convenience store in Wacol, where Ms Phillips made a phone call to her boyfriend after her own car ran out of fuel.

Police were led to Ms Phillips' murderer following a tip-off from his son Ian Mulvihill in May 2016.

Mr Mulvihill has recounted being ordered to drive a car he believed his father had used to hide Ms Phillips and said he was threatened after becoming suspicious when he heard sounds from inside the boot.

"He pulls a knife out of his little green bag, taps it on the window and says 'f*** off, I'll kill you both, get back in'," Mr Mulvihill told the Courier Mail.

"I don't know how she was in the boot. I don't know how she was taped.

"I lived with a murderer. I had to be careful about what I said, what I did."

Mr Mulvihill is not facing any criminal charges over the cold case.

He said his father confessed to killing Ms Phillips on his death bed and also said he killed other women.

An inquest held in 1988 found there was insufficient evidence to commit anyone to trial, however, Attorney-General Yvette D'Ath on Friday said she was satisfied it should be reopened after learning of the findings.

Police say they would have charged Mulvihill if he were still alive.

He died in 2002.
