A former security guard was sentenced on Thursday to serve 60 years in prison for killing a man during an argument at a Royal Farms in Southwest Baltimore, one of a series of high-profile shootings in 2022.

Baltimore Circuit Judge Kendra Y. Ausby handed down the maximum sentence on charges of second-degree murder and use of a handgun during the commission of a crime of violence against Kanisha Spence, 45, of Poppleton.

Spence received 40 years in prison for second-degree murder and 20 years for the other charges with the time to be served consecutively. Spence will not be eligible for parole for five years.

Spence had been working as a security guard for Maximum Protective Services when she fatally shot Marquise Powell at the Royal Farms on Washington Boulevard near Carroll Park on Oct. 30, 2022. She was found guilty at the end of August.

Powell was taken to Maryland Shock Trauma and died several days after the shooting. He was 26.

Surveillance cameras captured the deadly shooting. At the time, Powell’s sister, Tonuela Hill, was holding him back in a space just outside the front door of the convenience store.

Spence testified that Powell started “fussing and cussing” after she told him that the bathroom locked at 10 p.m. per store policy and later threatened to kill her. She said she was scared for her life, adding that “it all happened so fast that day.”

Powell’s loved ones have filed a wrongful death and survival action lawsuit against Spence, Royal Farms and Maximum Protective Services, which remains pending in Baltimore Circuit Court.
