The mother of a Golders Green student who died mysteriously in Germany in 2003 has had her complaint about the investigation into her son’s death rejected.

Lawyers representing Erica Duggan had filed a complaint accusing German prosecutors of ignoring a court order to reinvestigate the death in December 2012.

Jeremiah Duggan, a 22-year-old Jewish student, was found lying in a road near the city of Wiesbaden with fatal head injuries in 2003.

Ms Duggan believes he came to harm at the hands of a branch of the LaRouche international political movement, a cult suspected of fascist and anti-Semitic beliefs.

Last week, prosecutors rejected her complaint, insisting they did reinvestigate the case. They say her son committed suicide by running into oncoming traffic.

Ms Duggan said: “I don’t believe there is ever going to be a proper investigation by the German authorities. It’s 11 years and even with a court order they still don’t follow the order of the court.

“Here you have an extremist group that incites racism against the British and the Jews and the authorities are quite happy to say it’s no interest of theirs and they do not need to investigate this organisation.

“We go round and round in circles. No one in Germany seems to want to admit they made a mistake. At some point we have to break out of this cycle.”
