Seventeen-year-old Kemi Adeyoola was found guilty at London’s Old Bailey on Tuesday of murdering 85-year-old Anne Mendel a Jewish pensioner. The millionaire’s daughter stabbed Mendel 14 times at her London home. “Mrs. Mendel was a person whose whole life was taken up with kindness and giving up of herself for others,” her husband said in a statement. “The unjust end she met, having so much taken away in such an undeserving manner left us in total shock.” Adeyoola had written down her plans for the murder. “This was a premeditated murder which shows an unusual level of violence in a girl so young,” said Detective Inspector Steve Morris of the Metropolitan Police. The sentencing will take place at a further date.
