Alice Gruppioni, the Italian honeymooner killed in the hit-and-run accident in Los Angeles at the weekend, was 'the diamond of our lives', her younger sister Carlotta said.
Her family and friends said they were devastated to learn of her death, as her elder sister Naike and other family members flew to California at the weekend.
"My sister was the diamond of our lives,” the victim’s younger sister Carlotta said.
"Everybody loved her and she loved everybody. When you lose a diamond, you lose everything."
She spoke to the media outside the family home in Pianoro Nuovo, 10 miles south of Bologna.
Ms Gruppioni worked as a manager for the the Sira group, the family business, which makes radiators and she and her family are well-known in the region. Her father, Valerio Gruppioni, who runs the company was formerly president of the Bologna soccer team.
Silvano Scandellari, a childhood friend of Mr Gruppioni, said: "Alice was really special. She was always helping her neighbours and she invited everyone to her wedding, even the shopkeepers of the town. Rich and poor, for her it made no difference. She was really generous."
