Hannah Witheridge Trail Fund Hits Target
A fund set up to fly the family of murdered Hemsby student Hannah Witheridge to Thailand for the trail, has hit £10,000.
Hannah Witheridge and David Miller were murdered on the island of Koh Tao last September.
Two Burmese men have been charged with murder, and will go on trial in July.
The fund was set up by Hannah's sister Laura Witheridge, in order to pay for her family's flights, a translator and accommodation during the trial.
It took a £1,000 anonymous donation to meet their target, but today the figure sits at £10,686.
In a message on the page, Laura thanked everyone for "all the generous donations and support so far."
She added; "It is the selflessness and kindness of everyone around us that is going some way to restoring our faith in the human race."
