A Sussex killer who bludgeoned a lover to death with a hammer has lost an appeal against a murder conviction.
Christopher Hunnisett, 37, who now identifies as a woman called Crystal, killed Peter Bick, of Bexhill, in 2011.
Three judges were asked to consider whether new evidence that Hunnisett had a psychotic illness undermined the safety of the conviction.
But on Thursday they dismissed the appeal, saying there was "no proper basis to admit the fresh evidence".
Hunnisett handed herself in at Hastings police station on 11 January 2011, hours after killing 57-year-old supermarket worker Mr Bick.
