When he went away, wherever he went, it's hard to believe that he might be dead, because he was so upbeat when I last saw him. . . . Anyway, I thought maybe the police would ask me about him, but nobody did, and I didn't know what to do about that. I was scared. . . . I didn't know what happened to him, and when he didn't call me Saturday or Sunday, I thought he wasn't interested anymore." "When was the last time you heard from him?" Lucas asked. "Friday night, about . . . nine o'clock," she said."
