Mother and three children from Chinnor killed in A40 crash.

Three children and their mother have died after a car and HGV collided in Oxford on Monday night.

Emergency services were called at 9.50pm to the railway overbridge just to the west of Oxford following multiple calls from the public.

The family from Chinnor include a four-year-old girl, an eight year-old girl and a six-year-old boy.

A 29-year-old woman also sadly died at the scene.

A man and an 18 month old girl remain in a critical condition at the John Radcliffe Hospital.

Senior Investigating Officer Sergeant Dominic Mahon, of the Serious Collision Investigation Unit, based at Bicester, said:

“We are in the very early stages of our investigation into this incredibly tragic incident that has resulted in the deaths of four people from the same family.

“I would appeal to anybody who was driving in the area at the time of the collision and witnessed what happened to please contact 101, or make a report online, quoting reference number 43200321914.

“I would also urge anybody who has dash-cam footage of the incident or either of the vehicles just prior to the incident to please not share this publicly, but contact police with this detail.

“I would ask the public and media to please not speculate as to the cause of this horrendous incident. We will leave no stone unturned to ascertain what has caused this tragedy.

“The next of kin of the family have been made aware and are being supported by specially trained Family Liaison Officers.

“The thoughts of all of us at Thames Valley Police, along with our partners who have assisted at the scene or at the hospital, are with the families at this incredibly difficult time.

“I would like to also pay tribute to our officers, first responders and medical professionals, who dealt with this collision.

“Our officers and colleagues from the other emergency services were dealing with an extremely upsetting scene, and I would like to thank them for the work that they carried out overnight.

“This is an absolute tragedy, and again I would ask the public and the media not to speculate as to the cause, as we continue to support the families of all of the victims.”

The driver of the HGV, a 56-year-old man, suffered minor injuries.

As a close Chinnor community, we are all so saddened and shocked to hear about the tragic accident last night.

The Chinnor Community Church on the High Street has created a space for flowers to be laid for the family. CCC has a cross outside that anyone can come and lay flowers if they wish.

Our thoughts and prayers to everyone.
