POLICE investigating the disappearance of Warwick woman Gail Lynch are seeking the public's help to locate a man who may be able to assist with their enquiries.
Warwick police, with the assistance of the Homicide Investigation Unit, want to speak with Ian Hannaford, who has previously been interviewed while in custody in Toowoomba.
His whereabouts are now unknown but he has been confirmed as having been in a past relationship with Ms Lynch, last seen on Tuesday, July 3 at her Guy St unit.
She spoke to a family member that evening but has not made any contact since.
Sister Lyn McMillan said Ms Lynch's relationship with Mr Hannaford, who had his Rockville house searched and car seized by forensics last week, seemed to be happy but was not meant to be.
"They seemed happy, always holding hands, but when they broke up a few months ago he kept calling and asking her 'why' and she would say 'I just need time'," Ms McMillan said.
Police still urge anyone with information on the movements of his blue 2004 BA model Ford Falcon on the night of July 3.
They are also trying to locate a red rug missing from Ms Lynch's unit. The rug is described as three metres by two metres in size and has a gold patterned border.
Extensive searches in the Warwick area have failed to locate Ms Lynch.
Investigating police will hold a media conference in Warwick at 1pm today.
