Authorities responding to a call of shots fired at a southwest Atlanta home found a man with multiple gunshot wounds inside an open garage, the Atlanta Police Department said in a statement.

On Sunday, Simmons posted a video and picture on Instagram paying homage to Tennyson.
"Thank you for leaving behind my greatest gift . I'm hurting . I'm numb. Thank you for the out pouring of love everyone," her post read. "I cant believe I'm even saying Rest In Peace Sutton. I promise to hold SJ down in every way I promise."
