DETECTIVES investigating the brutal murder of Dawn Walker have displayed the clothing the fitness fanatic was wearing the last time she visited her gym in the hope it may jog the public's memory.

The dark blue waterproof sports jacket and green/grey walking trousers were revealed by officers yesterday - four weeks after the 37-year-old from Fornham St Martin, near Bury St Edmunds, was last seen alive.

And during a press briefing, murder squad detectives leading the hunt for Miss Walker's killer said they were confident her attacker would eventually be brought to justice.

“I am positive at the end of the day that we will find out who is responsible for this terrible crime, but I do not want to speculate on how close we are,” said Det Supt Roy Lambert, who is heading the inquiry.

“We still have not established a cause of death and are awaiting further tests. “These things can take a long time.

“But the thing with an investigation like this is not how quickly we find out who is responsible, but that we find the right person and all the evidence.”

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

She was last seen by a friend at around 9.30pm on Wednesday, February 2 at her home address in Oak Close.

The printing assistant, who worked at Abbey Hine in Bury, had visited her gym at the nearby Swallow Suffolk Hotel earlier that evening, where she was caught on CCTV in the clothing displayed yesterday.

“The jacket is not an exact replica, as these are no longer being manufactured, but it was very similar,” added Det Supt Lambert. “She wore it a lot and it was described as her favourite jacket, and she would wear it when she was out jogging or at the gym.

“By showing these clothes, we hope it will help jog memories. If anyone saw a lady on Wednesday, February 2, wearing similar clothing, then we would ask them to please come forward and contact us at the incident room.

“Every little piece of information may be crucial. The more people we can eliminate from our inquiry, the closer we will get to finding out who is responsible for this terrible offence.”

Det Supt Lambert, who said over 200 calls had been made to the incident room since the start of the inquiry, refused to speculate on the clothing Miss Walker was wearing when her body was found or where she was killed.

And he moved to reassure the public they “should not be overly-concerned” the killer may strike again, but he added “there is always a risk, although these sorts of offences are very, very unusual in Suffolk.”
