Sister of Christopher Alder on 25-year fight for answers

More than a decade after his death in police custody, the body of former paratrooper Christopher Alder was discovered lying in a mortuary. At the same time, in a grave bearing his name lay the body of a 77-year-old woman. No-one has ever been held responsible for either incident. Ahead of the 25th anniversary of his death, Mr Alder’s sister, Janet, spoke to the BBC about the psychological toll of her battle for truth and accountability.
