Tania Clarence, a 42-year-old mother was arrested on suspicion of murder after her three children, twin boys aged 3 and sister, 4 were found dead at the family’s £1.5million property in New Malden, south London on Tuesday evening.
Friends of Mrs Clarence, who is a graphic designer, said that the three children all had ‘life-limiting genetic conditions.’
