On Friday, a jury convicted Shirley of murder in the Jan. 10, 2017, killing, The Fulton County, Georgia, District Attorney’s Office said.
Shirley had just ended his shift working on Atlanta's Mercedes-Benz Stadium when 27-year-old Moore approached him and offered him sex in exchange for money, Fulton district attorney spokeswoman Nakell Williams said in a news release.
The two walked toward Underground Atlanta, where Shirley handed Moore $8.
When she told him it was “not enough,” Shirley reportedly grabbed Moore and threw her against a wall. She fell to the ground and Shirley kicked and stomped on her, authorities said. Shirley then pulled out a .22 caliber revolver and shot Moore in her face and neck, authorities said.
