OKLAHOMA CITY - The Oklahoma Court of Criminal Appeals has upheld the life prison sentence of a 26-year-old man convicted in the gang-related shooting death of a Tulsa barber.
   
The court handed down the decision Thursday in the case of Dezmen Smith, who was convicted of first-degree murder by a Tulsa County jury last year in the February 2015 shooting death of 41-year-old barber Keith Liggins.
   
Police said Smith and another man shot at rival gang members inside the Gifted Hands Barber Shop in Tulsa. The gang members inside shot back and a barber, Keith Liggins, an innocent victim was killed.  

Among other things, the court rejected claims by Smith that he was denied a fair trial.
