A film-maker whose body was discovered in a shallow grave in her garden had been strangled, a post-mortem examination has found.

The body of 34-year-old Laureline Garcia-Bertaux was found buried in Richmond upon Thames, south-west London, after she was reported missing from work.

Scotland Yard said that a post-mortem examination performed on Saturday gave a cause of death as "consistent with compression of the neck", while toxicology tests are pending.

Police urged anyone who saw or communicated with the French national between March 2 and Wednesday, when her body was unearthed, to get in touch.

Detective Chief Inspector Simon Harding, who leads the murder squad, said: "This may have been via phone calls, texts messages, WhatsApp or via any other social media platform.

"Laureline was known to local people as she walked her two dogs each day."

Detectives are pursuing a number of leads and a crime scene remains in place.
