Smith, who was part of the Oak Grove Posse gang, was suspected to have murdered another man in 2001 and was on the run when he committed the double shootings in 2002, first killing Janet Moore, a 41-year-old mother, at her house before he murdered 22-year-old Sarath Pulluru (also spelt Sharath Pulluru), a student and store clerk from India.

According to court sources, Smith reportedly grew up in a crime-infested neighbourhood where gang violence and drug activities were rampant.

[2] By 2000, Smith was already a member of the Oak Grove Posse, a local street gang active in Oklahoma City.

[2] By 2002, Smith was already on the wanted list for five felony cases, namely shooting with intent to kill, assault and battery with a dangerous weapon, assault and battery on a police officer, attempting to elude police, drunken driving and driving with a revoked driver's license.

On that day itself, Smith and his 29-year-old accomplice David Walter Burns were together with two men – 31-year-old Meldon Moore and 26-year-old Otis Payne Jr. – inside a sport utility vehicle outside the nightclub.

[4] Both Smith and Burns fled the car after the shootings, and the police would identify them and place them on the wanted list in connection to the murder of Payne.

[7][9] After shooting Moore to death, Smith cleaned up the house to remove any of his fingerprint traces to destroy evidence.

[7][10] Prior to this, in separate case, Smith's three fellow gang members – Teron “T-Nok” Armstrong, Kenneth “Peanut” Kinchion, and Dewayne “Pudgy-O” Shirley – went to rob a convenience store on the south side of Oklahoma City, but the robbery ended with the store owner, a Vietnamese man named Han Van Ho, shooting and killing one of the gang members, Armstrong, in self-defence.

[22] On September 20, 2003, the jury of nine women and three men recommended the death penalty for each count of murder in Smith's case,[23] as well as 85 years' imprisonment for the other lesser charges.

[24] On October 14, 2003, Smith was officially sentenced to death for both counts of murder by Oklahoma County District Judge Twyla Mason Gray.

Apart from the two death sentences, Smith was also handed a 85-year jail term for the robbery, burglary and arson charges.

After five days of trial, Smith was found guilty of second-degree murder before a jury at the Oklahoma County District Court, and sentenced to life imprisonment.

During the hearing itself, despite his claims of feeling sorrowful for the victims, Smith maintained his innocence, stating that he did not recall shooting both Moore and Pulluru, as he was high on drugs and his confession was not made voluntarily.

Mark Henricksen, Smith's lawyer, also pushed for mercy on behalf of his client on the grounds of intellectual disability, which was disputed by prosecutors, who opposed the clemency plea and argued that Smith remained a lingering menace to society, as he was said to have remained in contact with gang members behind bars and he was previously caught with weapons on death row as recently as 2019.

Moore's family released a statement, stating that justice has been served and they thanked all the authorities for pursuing the punishment for Smith over the past 22 years.
