Police have been carrying out a massive search for mother-of-three Gaynor Lord who has been missing for more than six days after leaving early from her work at a Norwich department store.

Here is a timeline of what we know of the last movements of the 55-year-old and of the investigation by Norfolk Constabulary into her disappearance in Norwich:

2.47pm – Ms Lord walks into London Street past the Cosy Club.

2.48pm – She walks along Queens Street and walks towards the cathedral.

3.22pm – Ms Lord is seen in The Close at the cathedral entrance – she then puts her coat on shortly before exiting through the archway.

3.23pm – She is seen walking away from the cathedral in Queens Street.

3.49pm – Ms Lord is seen walking along St George’s Street near to the Playhouse.

3.53pm – She walks along St Crispins Road towards Pitt Street.

8.10pm – Police are alerted to Ms Lord’s disappearance after her possessions were found in Wensum Park. She was identified by ID found in her handbag at the scene.

Gaynor’s clothing, that she had been wearing when she went missing, including a white shirt, yellow tank top plus two rings and her mobile phone and glasses, were found in the park in various locations. Her olive-coloured coat was discovered in the water.

Water-based searches, both surface and underwater have been carried out since Friday involving the Constabulary’s Marine Unit, Norfolk Fire and Rescue Service, Coastguard and Norfolk Lowland Search and Rescue (NorLSAR).

Saturday, December 9 – Wensum Park is closed off as specialist licensed search officers carry out extensive enquiries overseen by a police search adviser.

Monday, December 11 – Sonar equipment is deployed by Norfolk police’s marine unit, Norfolk Fire and Rescue Service, and the coastguard – but nothing was discovered.

Tuesday, December 12 – The search of the River Wensum resumes with drones and teams in inflatable boats seen on the river.

Wednesday, December 13 – Specialist underwater search teams from Lincolnshire Police arrive to assist Norfolk officers to search the river.

Thursday, December 14 – Norfolk Constabulary say they have not been able to establish Ms Lord’s state of mind with “any degree of confidence”.

Chief Superintendent Dave Buckley tells reporters that the force is keeping an open mind about what happened to Ms Lord but “everything we know is pointing to a high probability that Gaynor went into the water”.
