Jeremiah Joseph Duggan (10 November 1980 – 27 March 2003) was a British student in Paris who died during a visit to Wiesbaden, Hesse, Germany, after being struck by several motorists on a dual carriageway.

[1] German police concluded that Duggan had committed suicide after running several kilometres (miles) from the apartment in which he had been staying, then jumping in front of early-morning traffic.

A British coroner rejected a suicide verdict in 2003 after hearing the London Metropolitan Police describe the LaRouche movement as a political cult.

[1][7] In 2015 the coroner upheld that Duggan had been killed in the accident, but rejected a suicide verdict, adding that unexplained injuries suggested an "altercation at some stage before his death.

[20] Lyndon LaRouche and his German wife, Helga Zepp-LaRouche, ran a global political network of publications, committees and a youth cadre based in Leesburg, Virginia, United States, and in Wiesbaden, Hesse, Germany.

Duggan began seeing more of Chalifoux's group and was invited to attend a Schiller Institute conference near Wiesbaden, the LaRouche movement's European headquarters.

"[3] According to April Witt in The Washington Post, he told the audience that US President George W. Bush was an unreformed drunk (he is a teetotaler), Woodrow Wilson had founded the Ku Klux Klan from the White House, John F. Kennedy was killed by a domestic American operation, and the US was using the war in Iraq to "ignite catastrophic global warfare.

"[18]: 39–40  The plot to launch a world war was being influenced, he said, by people who "like Hitler, admire Nietzsche, but being Jewish ... couldn't qualify for Nazi Party leadership, even though their fascism was absolutely pure!

[18]: 40  A document from the Metropolitan Police, submitted to the first inquest, said the Schiller Institute and LaRouche Youth Movement blamed the Jewish people for the Iraq war and other global issues, and that "Jeremiah's lecture notes and bulletins showed the anti-Semitic nature of [the] ideology.

[18]: 40 [25][34] One of the Schiller Institute managers in whose apartment Duggan was staying told The Sunday Times that he and his roommate returned to the house around midnight.

She said he was speaking very quietly; sounded agitated and confused; complained that he no longer knew what was true and real; and that someone was conducting experiments with computers and magnetic waves, perhaps on him.

The roommate went too but pressed a doorbell by accident while looking for the light switch at the bottom of the stairs; he said this appeared to make Duggan panic and he ran off.

[25][33][38]: 179–181  The spot, near an Aral garage, was around five kilometres (c. three miles) from the apartment in which Duggan had been staying, and not far from the LaRouche offices in the Wiesbaden suburb of Erbenheim.

[41] Forensic reports commissioned by Erica Duggan suggested that he may have died elsewhere and been moved onto the road after the fact, a position the coroner rejected in 2015.

[8] Within minutes of Duggan's second telephone, Erica contacted the British emergency services and was advised to call her local police station in Colindale, Barnet.

[46]Under German law, Arlett said that he could investigate further only if there existed "concrete evidence of third-party involvement," and there was none; the Schiller Institute had been mentioned in connection with the death only because Duggan had attended an event of theirs.

[40][48] Duggan's body was flown back to England on 31 March 2003, where a non-forensic post-mortem examination was conducted on 4 April by pathologist David Shove.

[44]: 5  Shove found head injuries, bruising on the backs of the arms and hands, blood in the lungs and stomach,[20] and a full bladder.

A Metropolitan Police memo was entered as evidence: "The Schiller Institute and the LaRouche Youth Movement ... blames the Jewish people for the Iraq war and all the other problems in the world.

"[32] The coroner, Dr. William Dolman, delivered a narrative verdict: Jeremiah Joseph Duggan received fatal head injuries when he ran into the road in Wiesbaden and was hit by two private motor cars.

[38]: 235–236  Bayle argued that the Peugeot windscreen had been hit with a crowbar or a similar instrument,[44]: 35  while Canning wrote that he found nothing to suggest that the cars had made contact with Duggan.

Contrary to the claim that there was no sign that Duggan had come into contact with the cars, there were "traces on the underside of the Golf," according to Cecilia Ivimy on behalf of the Attorney General.

[54][61][62] The court heard from Catherine Picard, a French expert on cults, that Duggan might have experienced "intense pressure and psychological violence" at the conference, including one-on-one sessions, hours of lectures, and "being subjected to repeated conspiracy theories and antisemitic discourse.

"[61] Matthew Feldman, a historian at Teesside University and expert on the far right, testified that, if other participants had learned that Duggan was Jewish, British and had attended the Tavistock Clinic, "it would have been taken very seriously by the movement.

"[64] Duggan's family appealed unsuccessfully in 2006 to the Higher Regional Court (Oberlandesgericht) in Frankfurt regarding the decision to close the German police investigation.

The court said that a pedestrian leaving the LaRouche offices in Wiesbaden, in the direction of the town centre, would have reached exactly that junction in the Berliner Straße, and "would have had to cross the four-lane road if he did not want or was unable to turn back.

[65][66] Erica criticised the appointment of the same police officer who had presided over the case in 2003,[67] accusing the German authorities of "institutional racism" akin to that of the Stephen Lawrence murder inquiry.

[72] In 2007 the LaRouche movement published a letter from the Metropolitan Police, dated 14 July 2003, that it said was obtained under the British Freedom of Information Act, in which an officer wrote that he had been assured the case had been fully investigated in Germany.

"[73] In 2015 a spokesperson told Newsweek that the allegations were "utterly preposterous": At no time has Ms Duggan ever presented any evidence or facts that refute the findings of the German authorities concerning the suicide of her son.

Instead, over the last 12 years she and her representatives and collaborators have propounded wild conspiracies theories promulgated by the political enemies of Mr LaRouche in and around the British Monarchy and the circles of the now discredited former prime minister Tony Blair.
