From the article:
Andy Lopez was an eighth-grader at Lawrence Cook Middle School, where assistant principal Linsey Gannon said he played trumpet in the band. "Andy was a very loved student, a very popular, very handsome young man, very smart and capable,'" she said Wednesday.
Well, you obviously speak English, but the other two might apply based on this comment.
