A family friend of a pizza delivery driver who was recently gunned down in Baltimore says he had fled war-torn Syria to seek a better life. The killing of Khaled Heeba remains unsolved nearly two weeks after he died, the Baltimore Sun reports. His death is one of more than 40 homicides the city has seen so far this year. A family friend said Heeba escaped Syria’s civil war with his parents in 2016. He delivered pizzas to help support himself and his parents, and the family quickly acclimated to life in the US. Heeba, 31, was on his last delivery route of the night before he was shot in the chest on a sidewalk, the AP reports. "He left his own country because it was a war zone in Syria, just for him to end up getting murdered here," says co-worker Theresa Birmingham. "He was just really a sweet guy."
