BOISE, ID—Connie Barstow, 56, struggled Monday to appear interested in her 29-year-old daughter Andrea's just-completed independent documentary, Incident At Round Rock. "Is that you holding that microphone?" asked Barstow, watching her daughter's 94-minute investigation of a racially motivated 1996 beating in a small northern Idaho town. "I think I recognize that purple bracelet you always wear." Connie went on to state that Andrea has a lovely speaking voice and could have narrated the film herself.
