Appeal 20 years on from murder of Margaret Muller in east London

Twenty years on from the brutal murder of Margaret Muller in an east London park, detectives from the Met's Specialist Casework Team are re-appealing for any witnesses or anyone with information to come forward.

Margaret, 27, died after being attacked and stabbed while she was jogging in Victoria Park on the morning of 3 February 2003.

Despite a determined investigation into the circumstances, and various reviews of the case, no one has been convicted of Margaret's murder.

Detective Chief Inspector Amanda Greigof the Met's Specialist Casework Team, who look at unsolved murder investigations, said: "It is now 20 years since Margaret's shocking murder - an attack that left an indelible mark on the consciousness of a generation.

"I know people may think that too much time has passed for someone to be held to account for this heinous crime, but that is simply not the case.

"We are very keen to receive new information that, for whatever reason, someone has felt unable to provide previously. I want to appeal to anyone who has information that could help us to identify the person responsible for Margaret's murder to do the right thing and come forward.

"For two decades, Margaret's family have had to endure the agony of not seeing her killer face justice - this is something no family should have to live with and I urge anyone who can help to get in contact immediately."

The investigation was launched after police were called at 08.30hrs on Monday, 3 February 2003 to Victoria Park E9, after Margaret was discovered collapsed on a pathway between the rose gardens and the children's play area.

Margaret, of Wallis Road, E9, was an artist who had travelled from America to study at the Slade School of Art, University College of London.

A post-mortem examination gave a cause of death as multiple stab wounds.

Officers continue to appeal to anyone who was in the park on 3 February 2003, and who has yet to come forward, to contact them.

They are also keen to hear from anyone who may have seen anything suspicious in or around the Gascoyne Estate on the day of the murder.

Whilst detectives retain an open mind about the possible motive of the attack, intelligence suggests that Margaret could have been the victim of a failed robbery attempt.

As a result of previous appeals officers concentrated their efforts around the Queen's Gate entrance to Victoria Park.

They are particularly keen to trace anyone who witnessed a person walk past The Britannia pub, formally called The Victoria Park Inn, and enter the park through the Queen's Gate entrance at around 07:10hrs on the morning of the murder.

Alternatively, witnesses may recall a person sprinting back through the Queen's Gate entrance along Gascoyne Road and towards the Gascoyne Estate between 08:30hrs and 08:40 hrs, shortly after the murder.

Anyone who can assist is asked to contact the Specialist Casework Team on 0208 785 8267; if you wish to remain anonymous please call Crimestoppers 0800 555 111.
