Walid Chahine, an immigrant from Lebanon who had earned an engineering degree in Cleveland, had spent the day of May 26 playing with his 4-year-old son, running erands and mowing the lawn of his recently purchased home in Methuen. Chahine was 45 years old. He leaves a wife, Fida, and their four-year-old son Joseph. He dreamed of the day when he could stop driving a cab. "He realized that driving a cab was dangerous, but he had to provide for his family. He wanted to give them the best life, and he was doing just that when that man drove into him." "I want Daddy,'" said His Son (4 years old). "'Where is Daddy? How come he is not here? He usually opens the door and hugs me. Where is he?' And it seems like everyday, the same question [is] coming out of his mouth."
