A grand jury also indicted McKinney Wright Jr.. 22, and Quandarius Richardson, 18, on charges of attempted especially aggravated robbery. Richardson additionally was indicted on charges of theft of property over $10,000 and intentionally evading arrest in a motor vehicle risking injury or death.
Both are in custody without bond in the Shelby County Jail.
The incident occurred shortly before 7:30 p.m. on Sept. 27, 2018, in the 500 block of South Front Street where Trenary was walking on the sidewalk and talking on his cellphone. Witnesses said a white pickup truck stopped nearby and that a man exited the passenger side, approached Trenary from behind and shot him in the head.
The truck, which had been reported stolen, was located by police the next day in the Frayser area, but the driver refused to stop and drove away at a high rate of speed. The truck crashed at McLemore and Mississippi, injuring several occupants of two other vehicles.
Richardson was arrested at the scene, while Wright and a 16-year-old female were arrested the following day. Her case was handled in Juvenile Court.
Trenary was president and chief executive officer of the Greater Memphis Chamber.
The Criminal Court case involving Wright and Richardson is being handled by Deputy Dist. Atty. Gen. Ray Lepone and Asst. Dist. Atty. Melanie Cox.
