A nanny convicted of murdering two children she stabbed at their luxury New York City apartment has been sentenced to life in prison. In sentencing Yoselyn Ortega, 56, the judge described her as “pure evil” before handing her the maximum term. The bloody bodies of Lucia “Lulu” Krim, six, and her brother Leo, two, were found by their mother in a bathtub at the Manhattan flat on 25 October 2012. Ortega had pleaded insanity but the jury rejected her defence. On Monday, Ortega appeared visibly shaken as she apologised while addressing the court. Speaking in Spanish through a translator, she said she was “sorry for everything”, adding that she hoped for “a great deal of forgiveness”.
