Gunman Quincy Brangman must serve out his 25-year prison term after losing an appeal.Brangman, 33, was branded an “evil soul” by the judge who jailed him for trying to murder Nathan Darrell in Sandys last February.Brangman, a member of the Money Over Bitches gang according to the police, is believed to have targeted his victim for disrespecting the gang.His lawyer, Frank Phipps QC, sought earlier this month to get his conviction overturned or his sentence reduced.Mr Phipps argued that the evidence about Mr Brangman’s gang membership should have been inadmissible because it was “highly prejudicial”.He said the trial judge, Puisne Judge Carlisle Greaves, misdirected the jury on the law and the verdict of the jury could not be supported by the evidence.However, the three judges of the court of appeal disagreed, and yesterday delivered their ruling that the appeal has been denied.
