MURDERED fitness fanatic Dawn Walker had suffered serious burn injuries to her face when her body was found, it emerged today.

As detectives continued to investigate how the 37-year-old from Fornham St Martin, near Bury St Edmunds, was killed, fresh details about the murder surfaced last night.

Police had already admitted that, at some stage, Miss Walker's body was set alight but now it has emerged her face had also been at least partially burned.

Miss Walker's charred and semi-naked body was discovered next to the River Lark at Fornham Park at around 5.10pm on Friday, February 4.

She was last seen at her home at around 9.30pm on Wednesday, February 2 - and police have since revealed they are keen to speak to two people heard arguing just 45 minutes later close to the printing assistant's home.

A post mortem examination carried out in Ipswich following the discovery of her body proved inconclusive and further tests are set to take place to determine a cause and time of death.

Police continued their investigations yesterday while a mobile police unit remains stationed at Fornham All Saints Post Office.

Det Supt Roy Lambert, who is leading the investigation, said: "Over 30 officers remain committed to the investigation, while the unit is providing reassurance in the community. If anyone has any fears or concerns, they can visit that unit."
