Michael Adebolajo and Michael Adebowale have been jailed for murdering Fusilier Lee Rigby in Woolwich seven months ago.
While much is known about Adebolajo, little has been said about his 22-year-old accomplice Adebowale, who chose not to give evidence during their trial.
BBC London's Home Affairs Correspondent, Guy Smith, spoke to Jennifer Blake from Safe 'N' Sound Youth Project, who knew the teenage Adebowale well.
