Lily-Mae Jeffries: Dorset Police make new witness appeal

Lily-Mae Jeffries's family described her as the "apple of our eye"

The driver of a blue Renault Clio and a man in a fluorescent vest could hold clues into a road accident which left a five-year-old girl dead, police said.

Lily-Mae Jeffries and her grandmother were hit by two motorbikes when crossing the Weymouth A354 on 11 March.

Dorset Police are looking for the driver of a Clio "with a distinctive white stripe" and a man who administered first aid.

Lily-Mae was taken by air ambulance to hospital in Southampton where she died.

Anita Jeffries, 72, is described as being in a serious, but stable condition.

Police said no arrests had been made and the investigation into the collision was ongoing.

'Tragic accident'

Insp Debbie Marsden said she wanted the witnesses to contact Dorset Police to help with the investigation.

She said a total of three motorbikes were involved.

Lily-Mae's family, from Taunton, described her as the "apple of our eye" and said she made them "smile 100 times a day".

The girls were crossing the A354 Weymouth Way with their grandmother when the crash happened

Her sisters Kaycee-Ann, 10, Annabella, six, were also injured in the accident.

They received treatment at Dorchester hospital but have since been reunited at home in Somerset with their brother Anthony, eight.

Lily-Mae and her two older sisters had been left with her grandparents in Dorset while her parents attended a birthday celebration.

Her family said the girls and their grandmother were crossing the road so they could feed the swans and ducks.

They said: "From what we now know, there is no other reason than to believe this was anything but a tragic accident and our thoughts are also with the motorcyclists who were involved as they are no doubt feeling immense grief due to the nature of what happened."

In the tribute, the Jeffries family said Lily-Mae died in her "mummy's and daddy's arms".

They continued: "Lily-Mae's passing has left an unfillable void in all of our lives; she was the apple of our eye and made us smile 100 times a day with her appetite for life and her infectious zest and spirit."
