The separated couple have travelled with their daughter Hannah at their own expense to attend the trial, placing their lives on hold for nearly a month.
Fundraising efforts have stalled - with the Longley Family Trust having raised only $2225 - well short of the $35,000 cost.
The family have quietly watched from the public gallery, divided from Turner's supporters, as intimate details of their daughter Emily's life was heard.
Beneath them in the dock, swaggering Elliott Turner and his parents Anita, 51, and businessman Leigh, 54.
Emily's shocking death and Turner's sensational trial has attracted high-profile attention in Britain, with a media scrum of newspapers and TV crews awaiting the verdict in the historic county town.
Images of the beautiful young blonde woman who left Westlake Girls High and returned to her native England have been plastered across the pages of top-selling papers The Telegraph, and the Daily Mail.
Turner's parents are charged with perverting the course of justice amid claims they helped cover-up the alleged murder.
However, they can stroll around the courthouse only yards from the victim's family after not being detained in custody.
Turner's father was originally dubbed a wealthy jeweller in the press, but a troubled financial background has allegedly emerged.
The Turner home, which was first estimated to be worth £350,000 ($732,000), is a rundown detached property in Bournemouth and the Turners have moved between several houses in recent years.
The Honourable Mrs Justice Dobbs told jurors "stumps were being drawn" and to "enjoy their weekend".
The Longley family won't be.
