People living close to where Alice Gross went missing spoke today of their sadness after a body was found in the River Brent.
Police revealed significant efforts had been made to conceal the body and announced the hunt for prime suspect Arnis Zalkalns was now a murder investigation.
Scotland Yard said the body had not been formally identified but a statement from a senior officer left little doubt.
Commander Graham McNulty said it was 'devastating news' for everyone involved in the hunt for Alice.
The overnight developments came as a blow to people in Hanwell who tied hundreds of yellow ribbons to trees, lamp posts, garden gates, front doors and car wing mirrors.
Teacher Jane Hooper lives close to where the body was found and spoke for many residents.
