A mother is taking Germany to the Court of Human Rights accusing it of failing properly to investigate the mysterious death of her son, Jewish student Jeremiah Duggan, exactly eight years ago.

Mr Duggan's body was found beside the road in Wiesbaden on March 27 2003. The German police have consistently ruled it was suicide but a British coroner rejected the verdict.

The 22-year-old had been at a youth event organised by the far-right LaRouche group.

His mother, Erica, from north west London, will travel to Germany later this month and ask to meet the Wiesbaden prosecutor to discuss progress on the investigation and to lay flowers at the spot where her son was found.

Two Berlin lawyers, Serdar Kaya and Christian Knoll, will submit a final document to the Court of Human Rights accusing Germany of violating Article 2 - the right to life.

Mrs Duggan said: "I have letters to show that the prosecutor and the German police have treated me with a heartlessness and a disregard for the rule of law, which makes a proper investigation of a sudden violent death necessary.

"I appeal again to the people of Germany to uphold the right to life of every individual and to show it by properly investigating a highly violent sudden death." The family also feels that the British police have been "dragging their heels" in the inquiry.
