Detectives investigating the deaths of Fiona Anderson and her three children in Lowestoft have said they have continued to receive a positive response from local people following release of further CCTV images.

And the senior detective leading the investigation said this morning his team is satisfied that it does need to look for anyone else in connection with the deaths.

Yesterday police issued colour CCTV stills which showed Miss Anderson, 23, outside the Fyffe Centre in Belvedere Road, Lowestoft.

The images were captured at about 6:20am on Monday and show her wearing a long white coat and black shoes. She has long dark hair and is visibly pregnant.

Later that morning, at just after 8am, police were called to the multi-storey car park on Gordon Road, where Miss Anderson was found with severe head injuries.

She was pronounced dead at the scene.

Enquiries into the incident led police to an address in London Road South, where the bodies of her three children – Levina, aged three; Addy, aged two and 11-month-old Kyden – were discovered.

A cordon around this address remains in place – and is likely to remain in place over the weekend.

Detective Superintendent John Brocklebank said: 'Again, we have had an overwhelmingly positive response from the community to our appeals for information, following the release of these CCTV images of Fiona.

'More than 15 people have been in touch as a result, offering us information.

Our appeal to trace Fiona's last movements still stands – so if you saw her early on Monday morning, please get in contact.'

Extensive enquiries into the deaths of Miss Anderson and her three children have taken place over the last few days, including house-to-house enquiries and forensic examinations.

Det Supt Brocklebank said: 'While there are some important pieces of information which are still awaited, such as the results of further tests following the post-mortem examinations on the three children, we have reached an important stage in our investigation.

'I am now satisfied that we are not looking for anyone else in connection with the tragic deaths of Fiona and her children.

'We will continue with our enquiries over the next few weeks on behalf of the coroner, so that inquests may be held in due course.'

Anyone who saw Miss Anderson or has any other information should contact Suffolk Police on 101.
