Sharron Phillips mystery: 'Siblings fear dad involved'

SHARRON Phillips' siblings have called for police to search bushland near their parents' home amid fears their late father may have been involved in the cold case killing.

Sharron, who was 20 at the time, disappeared from Wacol on May 8, 1986.

Despite a $250,000 reward being posted, her body has never been found and no one has been charged, despite hundreds of interviews and leads by police.

Now Sharron's oldest sister and brothers have broken their silence and publicly questioned whether their father was involved.

Fairfax reported on Friday that Sharron Phillips' brothers and her older sister doubt their father's claim that he was collecting "one of their trucks" from the New South Wales town of Gilgandra the night Sharron disappeared.

Bob Dallow, a retired detective inspector, also had doubts about the alibi.

Bob Phillips died in August 2015 after a lengthy illness.

Speaking to the South-West News in May that year, Mr Phillips said he remained hopeful he would find out what happened to his daughter almost 30 years ago.

"I know someone must know something. Please come forward. We need to know what happened," Mr Phillips said.

Mr Phillips said not knowing what happened to Sharron, nicknamed "Big Bird", had destroyed the family, particularly his wife Dawn who suffered from severe depression and died in 2010 aged 54.

Fairfax on Friday reported the detective's wife, Kay Dallow, says she was given an admission by a heavily sedated and ill mother of Sharron: "Bobby killed Sharron and put her in a box. And I want him to kill me and put me in a box too," she was alleged to say at her son "Charlie's" wedding in 1991.

Police could not act on the alleged admission because of the credibility of the statement given the heavy medication. reported that the head of Queensland's Cold Case Squad, Acting Inspector Glenn Terry, agreed on Thursday to send an investigator to meet the Phillips' siblings.

A decision on whether or not to search the Riverview block would depend on the information investigators received.

Sharron Phillips, then 20, was last seen about 11pm on Saturday, May 8, 1986, at a telephone box near Wacol railway station.

A person matching her description was seen by a number of people between the station and where her car was found.

Her yellow Datsun Bluebird sedan ran out of petrol at the divide between Ipswich and Brisbane on the motorway.

She walked across the motorway to the Wacol Army Barracks but soldiers said there were no telephones she could use.

After the Queensland Times ran a story to mark the 20th anniversary of her disappearance, an anonymous letter was sent to the paper saying Sharron was killed because she witnessed strange sex acts being performed at the barracks.

After she left the army barracks, she phoned Martin Balazs, a man she met a few days earlier, and asked him to pick her up from a nearby service station.

Mr Balazs said he at first wasn't sure which service station to go to, then his car got a flat tyre.

After he got going he saw Sharron's car beside the road, but didn't see anyone so he drove home.

He was interviewed by police but was eliminated as a suspect.

Signs bearing Sharron's name were put both sides of the motorway near where her car was found but for some reason her name was misspelt 'Sharon'.

Main Roads said the signs were removed in late 2007 after consultation with Ms Phillips' father Bob.

"Mr Phillips was agreeable with the temporary removal, as long as the signage was reinstated at the same location as part of the upgrade," a spokeswoman said at the time.

Anyone with information about Sharron Phillips' death is urged to call to Crime Stoppers on 1800 333 000.
