A former Harrow pupil found dead on a German motorway did not commit suicide despite police in the country insisting he killed himself, a coroner has ruled.

Coroner Andrew Walker said Jeremiah Duggan, 22, “received fatal injuries following a collision with two cars” on a road near Wiesbaden in 2003, and “totally rejected” suicide as a cause of death.

There were also a “number of unexplained injuries” suggesting there might have been an “altercation at some stage before his death”.

And he added that revelations by Mr Duggan that he was a British Jew to members of a far-right organisation “may have had a bearing on his death”.

It had been suggested on the first day of the inquest, that took place at North London Coroner’s Court, that the crash had been a “constructed set-up”.

The coroner’s narrative verdict said: “Jeremiah Duggan received fatal injuries following a collision with two cars on the Berliner Strasse and died in a road traffic collision.”

Mr Duggan had attended a conference run by a right-wing organisation called LaRouche in the days leading up to his death.

The verdict continued: “Against the backdrop of the start of the Iraq war, together with Mr Duggan expressing he was a Jew, British and questioning the material put before him, may have had a bearing on Mr Duggan’s death, in the sense that it may have put Mr Duggan at risk from members of the organisation and caused Mr Duggan to become distressed.

“I totally reject that this was a suicide.”

The verdict follows a 12-year battle by the family, led by Jeremiah's mother Erica, to have the original ruling overturned, after the High Court ordered a fresh inquest in May 2010.

It said in a statement: “The pressure should now be put upon the German authorities to ensure this powerful and dramatic narrative verdict leads to deeper investigation in the country where Jeremiah was killed, including the role played of the LaRouche organisation.

“We hope Jeremiah’s legacy will be that the strong message that such extremist organisations exist which target university students for recruitment has been heard so that the dangers they pose can be avoided.”

His mum Erica Duggan said she will search for answers, vowing to “fight on”.
