Prosecutors allege Pollard, a “Neighborhood” gang member, intended to rob Clark with the help of Calton, a gang associate, and “Neighborhood” gang members Tommy Long and Sean Anderson.
Calton said Pollard and Long had handguns. He said the four assailants waited on the side of the aunt's house for Clark, who was in his car before he was approached.
The witness said he waited by the side of the house while Pollard ran to the front of Clark's car and Long ran to the back of the vehicle.
Calton said he heard someone telling Clark to get out of the car followed by gunshots. Clark was shot once in the chest and died at the scene. His car rolled down the driveway and came to rest in a field across the street, his aunt said.
Long, 20, of Oklahoma City, was convicted of first-degree murder in November and was sentenced to life in prison. Anderson, 22, of Edmond, pleaded guilty to a conspiracy charge and received 10 years in prison plus 10 years for violating his probation in an unrelated case.
Calton, of Oklahoma City, pleaded guilty to a murder charge and was sentenced as a youthful offender because he was 14 when Clark was killed. He could be sentenced to prison for life if he fails to complete a treatment program administered by the state Office of Juvenile Affairs.
Clark worked for Asplundh, a nationwide tree-trimming company that clears utility rights of way. The company uses orange for its vehicles and work clothes.
