Five people remained in hospital on Wednesday morning following the horrific collision, close to the point-to-point turn off at the Haverhill end of the first dual carriageway.

Suffolk Police force operations inspector Bruce Gent said there had been a concern that one of the injured, a child, may not survive.

David Bocking, 43, of Halstead, Essex, was in his Peugeot 806 estate with Daniel Bocking, 14, and Stephen Bocking, 13, as well as a 39-year-old woman and a nine-year-old girl when it collided with a silver Volkswagen Golf at 3.25pm on Saturday.

The girl and the woman were both in critical conditions on Sunday night, while a 60-year-old man from the other car, a silver Volkswagen Golf, was also described as being in a critical condition.

He was travelling with a 50-year-old woman, who was in a serious condition on Sunday night, and a 13-year-old girl who was in a serious but stable condition.

The families have asked Cambridgeshire Police not to release the conditions of the injured parties.

Fire crews, ambulances and police officers from around the area, in Cambridgeshire and Suffolk, attended the scene on Saturday afternoon.

The road was shut for six hours while police investigations continued and paramedics and fire fighters worked on rescuing the injured and deceased from their cars.

Days after the crash there was still evidence of skid marks and damage to a nearby fence while a police incident sign, flowers and a written tribute to Daniel also marked the scene.

The tribute said: “I didn’t really know you too well but well enough to be writing this.”

It added: “Have fun wherever you are now. We will miss you.

“Look after your dad and brother. I’ll look after James for you.”

Police are appealing for anyone who saw the crash, or either of the cars in the minutes leading up to the crash, to call them on 0845 456 456 4.
