A mother-of-three who died after a crash on the A47 near Dereham has been remembered by her family as always having a smile on her face and being loved by everyone she met.

Kim Utting, 52, was killed on Valentine's Day morning as she and her daughter, Emma Herring, were travelling towards Norwich.

Mrs Utting, of Litcham, died at the scene, and her 30-year-old daughter was taken to the Norfolk and Norwich University Hospital where she was treated for her injuries and later discharged.

A family statement said: 'Kim always had a smile on her face and was a very kind, caring and affectionate person. She was loved by everyone she met and will be very sadly missed by all her family, friends and those who knew her through her passion – the dog show scene.'

Mrs Utting was born in Shipdham, daughter of Donald and June Dodd, and sister to Susan Boldero and Peter Dodd, of D D Dodd and Son, the fuel supplier company.

In 1981 she married Ken Knight and they had two children together, Emma and Jamie.

She later married David Utting and had a son Dudley, 11.

Mrs Utting was a prominent figure on the dog show scene, with dogs described by her family as her 'passion' and she won a major prize at Crufts in 2008 with her mastiffs.

Police said Mrs Utting was a passenger in a green Peugeot 406 travelling towards Norwich, when the crash happened between Draytonhall Lane and the A1075.

A man in his 20s who was driving in the opposite direction in a red Skoda, thought to be from Dereham, is being treated at Addenbrooke's Hospital in Cambridge for head, lung and arm injuries.

His condition is described as critical.

Police want to speak to the driver of a small black Peugeot hatchback car which was seen driving erratically towards Norwich and failed to stop at the scene at about 10.30am.

The black car overtook the green Peugeot and a white, long flatbed lorry.

Police also want to hear from the driver of the white lorry, which appeared to have something fluorescent on one of its wing mirrors and also failed to stop.

Anyone with information should call police on 101.
