The deaths of two teenagers run over by a ute as they camped out after a party had "broke 1000 hearts", says one of their grief-stricken mothers.
Early on Tuesday morning, 19-year-olds Will Dalton-Brown and Eliza Wannan were sleeping beside a ute on a farm near Molong, in central west NSW, after celebrating Australia Day at a gathering of friends.
Police allege a 17-year-old boy reversed over them in his ute as he prepared to leave the Belgravia Road property about 5am.
The injured pair, whose long-time friendship had recently taken a romantic turn, was rushed to hospital, where they died within hours of each other on Wednesday.
Lee Dalton said her son was on the "cusp of life" but now her worst nightmare has been realised.
"The deaths of Will and Eliza broke 1000 hearts on Wednesday - four of them being their parents," she told AAP.
"It's every parent's worst nightmare. For us it has become a reality.
"Will was, and will remain, 19 years and two days old."
Ms Dalton said her son had recently returned to Australia after a gap year in which he spent three months travelling around southern African by himself.
He financed his trip by chopping and selling firewood.
He and Eliza, former students of Orange's Kinross Wolaroi School, were both about to start university courses.
Nedra Burns, a friend of the Wannan family, said Eliza's parents were "absolutely devastated".
Eliza's MySpace page said she was "supposed to be born in the 60s" and loved to laugh at her own jokes and find the good in everyone.
Police took statements from everyone in the area at the time of the tragedy.
The 17-year-old driver was questioned and released pending further inquiries.
