A 30-year-old African American man from Houston has been charged with capital murder for allegedly killing a Caucasian police deputy in Harris County, Texas. The suspect appeared in court for his arraignment on Monday.

During the hearing, Harris County District Attorney Devon Anderson presented the details of the murder case being brought against Shannon Miles. Miles has yet to enter a plea in response to the charges. The Houstonian has been accused of killing Deputy Darren Goforth by shooting him in the back last Friday evening while the deputy was filling his police vehicle with gas.

Officer Discovered Face Down in a Pool of Blood

Authorities found the deceased officer next to his police car, in a pool of blood with multiple gunshot wounds in his back. They found 15 40-caliber bullet shell casings on the ground around the officer.

Surveillance video footage reveals the officer being shot in the back of the head by a black male. Footage then shows the same black male standing over the top of the officer and shooting him with more rounds.

After searching the suspect's garage, police found a 40-caliber handgun loaded with the same kind of ammunition they found at the crime scene. Further testing by forensic specialists matched the handgun to the bullet casings found at the scene.

Charged Man Discharged Entire Weapon Into Officer

During the arraignment, District Attorney Devon Anderson said that Miles discharged all of the weapon's ammunition into the deceased officer. Witnesses have also identified Miles as the murderer who shot the officer.

That said, Miles appears to have an alibi in his mother, who claims that she was shopping with her son at the time of the alleged murder.

The sheriff of Harris County believes that the shooting of the officer was linked to anti-police sentiment in the area, which has been strengthened after recent protests. According to Sheriff Ron Hickman, "We've heard black lives matter; all lives matter. Well cops' lives matter too ... At any point where the rhetoric ramps up to the point where calculated cold-blooded assassination of police officers happen(s), this rhetoric has gotten out of control."
