A Belgian surgeon who has admitted euthanasing several patients illegally in her own country is being questioned over the death of a 74-year-old patient in France. Police allege that the doctor deliberately gave the woman an insulin overdose and she died two days later. The doctor suffers from depression and alcoholism and was imprisoned for four months in Belgium for fraud. She has also admitted that she euthanased several patients, including her own grandmother, before Belgium legalised euthanasia in 2002.
