Derrick Boston
Chattanooga Police have made a second arrest in the homicide of Desmond Clay.
Police earlier arrested Desmond Trammell with the help of a new Real Time Intelligence Camera.
On Tuesday, police took Derrick Boston, 26, into custody, saying he was a passenger in the vehicle driven by Trammell.
Boston was charged with criminal responsibility for facilitation of a felony.
Police said a white Hyundai Sonata was seen on the camera following the victim's vehicle just prior to the shooting.
Clay was shot in the back and died within the hour.
Police afterward located Trammell at his residence in the driver's seat of a white Hyundai Sonata with tinted windows and a sunroof as seen in the video. A handgun was found in the center console of the vehicle.
Police said Trammell, 20, of 803 E. 49th St., admitted chasing the Clay vehicle and said the gun with him was the murder weapon. He claimed that Boston was with him and was the one who shot the victim.
A witness said Boston called Trammell and told him that Clay was across the street and to bring that "thing" (gun) to the Midnight Oil gas station.
Police said Boston can be seen on the Midnight Oil video exiting a black Dodge Caliber and getting into the passenger seat with Trammell.
Trammell's charges include criminal homicide, unlawful possession of a firearm, and unlawful possession of a firearm during the commission of a dangerous felony.
The 39-year-old Clay was shot and killed while driving in a vehicle on Wilcox Boulevard on July 26.
At 10:18 p.m., officers responded to a person shot call at 3399 Wilcox Blvd.
The victim was located in a vehicle that crashed into a business. He had suffered multiple gunshot wounds.
He was transported by Hamilton County EMS to a local hospital. He died at the hospital.
His twin brother, Demond Clay, was shot in 2010.
