Man claims Sharron Phillips' death was an accident
LATEST: POLICE now believe Sharron Phillips may have been killed by a taxi driver after her car ran out of fuel on Ipswich Rd.
After three decades of the case being treated as a homicide investigation, it has now been revealed it could be treated as manslaughter after a member of the public came forward with "specific" new information.
The information is believed to have been supplied by the taxi driver's son, who said his father may have been the one to blame for 20-year-old Sharron's death.
The man allegedly told police his father accidentally hit Sharron as she was walking along the road the night she disappeared in 1986.
He said his father then phoned him to ask for help to dispose of the body.
Police said the man came forward with the new information after being prompted by his conscience and that his father passed away a number of years ago.
A number of Sharron's eight siblings still hold suspicions that her father Bob Phillips was responsible, saying the alibi he gave detectives at the time did not stack up.
Investigations are continuing.
Anyone with information of Sharron Phillips' disappearance should contact Crime Stoppers on 1800 333 000.
EARLIER: Homicide detectives have spent a second day at the site they believe could hold the key to one of the state's most enduring murder mysteries.
Police revealed this week a new witness had come forward and provided them with highly credible information surrounding the 1986 disappearance of Sharron Phillips.
Police said the person had come forward in the past two weeks after their conscience got the better of them.
They said the new witness had not been spoken to previously and would not divulge what relationship, if any, the person had with Ms Phillips.
Ms Phillips, 20, disappeared on May 8, 1986 after her car ran out of petrol about 11pm near the Wacol army barracks.
She had called her boyfriend from a service station and asked him to pick her up but when he arrived, she was gone.
Ms Phillips has not been seen or heard from since and is presumed to have been murdered.
No one has been charged over her death.
Police immediately acted on the new information and secured a crime scene warrant to dig up storm water drains on Cobalt St at Carole Park.
An anthropologist is also at the site to assist police should they make a discovery when sifting through more than 100 cubic metres of soil.
Detective Inspector Damien Hansen told media earlier this week police had started digging at the site after receiving credible new information which correlated with previous investigations.
He said the person told police Ms Phillips was murdered and her body left in the stormwater drain - information that had been verified in some detail during previous investigations.
EARLIER: The sister of Ipswich woman Sharron Phillips, who vanished in 1986 after her car ran out of petrol, is pleading for a new inquest into her death.
Detectives and forensic teams hunting for Ms Phillips' body began excavating a site on an industrial estate at Carole Park in Ipswich yesterday after a tip-off from a member of the public.
But in her first TV interview, her sister Donna Anderson repeated calls for detectives to instead hunt for a grave at the family's old home at Riverview, Ipswich.
She also repeated her suspicions that her father Bob Phillips was responsible, saying the alibi he gave detectives at the time did not stack up. Read more at ABC News
