Ebony Wallace hasn't left her house much since her son Wauynee, 17, was killed last month - shot once in the back of the head by someone who disappeared into the night. She can't stand to look at her neighbors' faces. She's certain someone in Camden's Whitman Park section knows why her son was killed. She's sure she'll see it on their faces. "I know guilt when I see it," she said. "And I'm going to be wondering, 'Why are you looking at me guilty?' " Investigators don't have a motive in Wauynee Wallace's killing, but they see no link with a recent gang- and drug-turf battle that the city's police chief has blamed for a spike in violence.
