A series of events in Germany will honour a young student from Golders Green who died in mysterious circumstances five years ago.

Erica Duggan, 61, has been fighting for an inquest for her son, Jeremiah, since he was found dead on a motorway in Wiesbaden on March 27, 2003, after attending an event organised by the Schiller Institute.

The first inquest, in November 2003, was inconclusive and found Mr Duggan had been in a "state of terror" when he died.

On March 27, family and friends of the 22-year-old will travel from Britain, France and Germany to gather in Wiesbaden to raise awareness about his death and alert the town to the need to protect youngsters against groups who use deception to gain their support.

The day will begin with a memorial walk along the five-kilometre route Jeremiah is believed to have run before he died.

There will then be a town meeting to discuss whether the LaRouche movement – an international political and cultural organisation run by the founder of the Schiller Institute, Helga Zepp-LaRouche, and her husband Lyndon – is a danger to society.

Affected families from Germany, UK and France will speak about young people they claim were taken to Germany to be trained to be "militants" for the movement.

Dr Matthew Feldman from Northampton University will speak about a rise of extremism and antisemitism in Europe.

The meeting will be moderated by Ursula Caberta, an agency of the interior ministry of Hamburg, established to help people affected by cults and provide information.

Mrs Duggan said: “This event is about exposing what’s been going on for the past 30 years.

“After six years of struggling, we are still no closer to finding out what really happened to Jeremiah. The least we can do is expose some of the dangers faced by other families in the same position.”

For six years Mrs Duggan has battled to have the investigation into her son’s death re-opened. The Attorney General rejected her request to open a new inquest last year, but in October the High Court gave her the right to question this verdict.

She has also been waiting three years for the Karlsruhe Constitutional Court to judge whether Mr Duggan’s human rights were violated by not having a full investigation into his death.

Mrs Duggan said: “I absolutely feel betrayed by my country. The Attorney General had everything before her and turned us down. Now we have to resubmit all the evidence and start all over again.

“We have waited and waited, and what are we waiting for? For the simple right to have an investigation. That’s not justice.

“What does that say about our democratic system that British people have to go to Germany to make a protest?”

New evidence submitted by Mrs Duggan since the first inquest includes reports by three crash investigators and a forensic photographer.

The coroner's pathologist, who carried out a post mortem examination on his body in the UK, said his injuries were consistent with being beaten around the head.

The LaRouche movement and Schiller Institute deny having any involvement in the student’s death .
