And Alloway's upbeat personality will be dearly missed, as this heartbroken family tries to find some blessing in their loss.
"He went there and talked to my mother, he said Granny, I love you. What are you cooking for Thanksgiving; but he won't be there."
But his parents will; remembering the young person who brought some much life into their home and the senseless violence that took him away.
"My son has been taken away from me by someone who didn't care about lives at sake. I'm hoping justice will be served for my son for the future he didn't get to have."
And his parents thrived on his energy. Now, that energy is giving them strength to tell his story.
"Marcus had a way to your heart, he had a way to encourage me when I was down."
Two things were at the center of Alloway's heart - his family - and his school - Sidney Lanier.
"He said mom, I want to grad as a Poet of Lanier. He loved Lanier High School."
After high school Alloway had planned to become a firefighter, simply because he wanted to save lives.
