A Polish decorator serving an indefinite sentence for killing a Stamford Hill Jewish pensioner in a robbery at her home has lost a test case appeal against his conviction.
Kuba Dlugosz, 35, left 83-year-old Eveline Kelmenson with her ankles and wrists taped up after he and another man forced their way into her home in a desperate hunt for valuables to steal.
He denied any wrongdoing, but was convicted at the Old Bailey in June 2011 of manslaughter, burglary and robbery and jailed indefinitely.
His lawyers challenged the admissibility of controversial DNA evidence gathered from the scene.
