An ex-police officer pleaded guilty today (Monday) to causing the death of a 13-year-old girl by careless driving in Stansted Mountfitchet.

Caren Klein, 35, of Frambury Lane, Newport, killed Chiara Sanfellippo when she hit the Herts and Essex High School pupil with her Suzuki Alto car, on Cambridge Road.

Chiara, who loved boyband One Direction and horse riding, had just got off a bus and was trying to cross the road when the collision took place on October 16, 2013. She died of head injuries.

Former Metropolitan police officer Klien, pleaded guilty at Chelmsford Crown Court and is now waiting to be sentenced.

She was remanded until November 14 on unconditional bail for pre-sentence reports by Judge Anthony Goldstaub, QC, who described the incident as a “catastrophic accident.”

Before a packed public gallery, Judge Goldstaub said: “I’ve read the court papers and I’m sorry to hear of the death and the court expresses its condolences.

“She (Klein) was slightly in excess of the speed limit and the main cause is the child runs out. It shows how careful one must be driving a car. A lack of concentration can cause a catastrophic accident.”

He added that it was likely Klein would be sentenced to a community order.

Speaking at the time of Chiara’s death, headteacher at Herts and Essex High School, Cathy Tooze said: “We have been deeply saddened to hear the news of Chiara Sanfilippo’s death. She has been at Herts & Essex since Year 7 and was a popular and high-achieving student.

“Chiara made many friends and always had a kind word and a smile for others. She was well liked by her peers, who appreciated her sense of humour and positive outlook.

“Chiara will be sadly missed by all who knew her. We send our condolences to Chiara’s family.”
