EIGHT years on from the brutal stabbing of artist Margaret Muller, detectives are still hunting her killer and are offering a reward of up to �20,000 for information leading to a prosecution.

American Margaret, 27, was stabbed to death in Victoria Park on February 3, 2003 and despite having made several arrests over the years, police are no closer to finding her killer.

Margaret, who was studying at the Slade School of Art at University College London and regularly jogged in the park, was discovered collapsed on a pathway between the rose gardens and the children’s play area at 8.30am.

Cos believe she may have been the victim of a failed robbery attempt.

Det Chief Insp Nicola Wall from the Met’s homicide and serious crime unit said: “Margaret was a talented young woman with a bright and exciting future ahead of her. That was all taken away when she was brutally struck down in Victoria Park eight years ago.

“Officers have worked tirelessly on this case and have managed to sift through literally hundreds of pieces of information and leads.

“Despite the tremendous support from the local community we know that some people still hold vital information about Margaret’s murder.

“Together with information already gathered they could help us achieve justice for Margaret and her family and friends. We urge anyone with new information to come forward and assist us.”

Officers are still appealing 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.

Officers have been concentrating their efforts around the Queen’s Gate on the north side of the park. They are particularly keen to trace anyone who witnessed a person walk past The Britannia pub, formally called The Victoria Park Inn, around 7.10am.

Margaret was white, and had short dark brown hair. She was wearing a pair of black leggings, a green fleece top a pink woolly hat and grey trainers.

Witnesses may also recall a person sprinting back through the Queen’s Gate, along Gascoyne Road and towards the Gascoyne Estate between 8.30am and 8.40am.

Anyone who can assist is asked to contact the Incident Room on 020 8345 1585 or Crimestoppers anonymously on 0800 555 111.
