The mother of Jewish student, Jeremiah Duggan, who died under suspicious circumstances seven years ago, has praised a Channel 4 documentary about his death but added it could have been “braver”.

Mr Duggan was found dead aged 22 on a highway near Wiesbaden, Germany in March 2003 while attending a youth event organised by the far-right LaRouche group.

A Cutting Edge documentary on Thursday, called Lost Abroad: The Parents’ story , follows Mrs Duggan through Germany and France as she retraces her son’s final steps.

Mrs Duggan said: “The documentary raised important questions which urgently need to be answered, but it also leaves out many questions such as where he was when he made the final phone call to me and why he was running away.”

Last month, an application for a new inquest into his death was filed.
