His uncle worried he was cooped up in his room too much. The few images of him found easily online suggest he had a fascination with white supremacy. And for his birthday this year, his father bought the young man a pistol, the uncle said.

Dylann Roof, 21, was arrested on Thursday on suspicion of having fatally shot nine people at a historic African-American church in South Carolina on Wednesday.

Those who know him described a withdrawn, troubled young man. Roof himself told a police officer who was arresting him earlier this year for illegal possession of prescription painkillers that his parents were pressuring him to get a job.
