Police are trying to establish the circumstances surrounding the death of a Glasgow man whose mother took him to a Swiss clinic to die. Helen Cowie told BBC Scotland's Call Kaye show she helped her son Robert, 33, commit suicide after he was left paralysed from the neck down. Mrs Cowie, of Cardonald, Glasgow, said her son went to Dignitas in October and "had a very peaceful ending". Strathclyde Police said they were not investigating the death at this time. However, a spokesman added: "The matter is being given consideration in an effort to establish the circumstances." Mrs Cowie said her son was paralysed in a swimming accident three years ago.
