A confrontation in a Tulsa apartment complex parking lot turned deadly on the morning of August 18, 2014. Verdell Delo Walker III, 21, and his friend Tiara Sawyer, 21, had been with Isaac Luna Ashton and his girlfriend earlier that morning; the girlfriend had given them a ride to a tag agency. When the group returned to the complex at 47th and Darlington, a verbal argument broke out between Walker and Ashton.

Witnesses say Ashton became the aggressor after Walker cursed at him. Neither Walker nor Sawyer was armed when Ashton produced a .38 special handgun and opened fire. Walker was shot in a manner consistent with being fired upon while already on the ground; Sawyer died of a single gunshot to the left temple. A search of Ashton's mother’s home recovered a handgun that ballistics matched to the bullets recovered from both victims.

Isaac Luna Ashton was tried; eyewitness testimony and ballistic evidence were presented. A jury convicted him on two counts of first-degree murder and unlawfully carrying a weapon, and he received two consecutive life sentences without parole.
