LITTLETON, Colo. (AP) -- Columbine High School junior Kim Blair could not believe that what happened at her school one month ago happened again elsewhere. ``What do you do now?'' Miss Blair, 17, said. ``It's happening again. What school is going to be next? It's kind of scary.'' In Conyers, Ga., on Thursday, a student opened fire inside Heritage High School, shooting and injuring six students. On April 20 at Columbine, Eric Harris, 18, and Dylan Klebold, 17, shot and killed a dozen students and a teacher, then killed themselves. Many classmates and relatives of Columbine victims believe the country may be in for more such shootings. ``I have said since this thing happened that they better beware because it's going to happen again and again,'' said Michael Shoels, whose son, Isaiah, 18, died at Columbine. ``This has some kind of organization to it, so we better beware,'' Shoels said in an interview. Zoe Bruschke, grandmother of Columbine student Grant Taylor, 16, who escaped, was shocked by the Georgia shootings. ``There may be more,'' Ms. Bruschke said. ``Where does this start? Aren't there warning signs?'' Miss Blair was troubled that anyone would want to emulate Harris and Klebold. ``I don't like how people are trying to copycat the Columbine shooting,'' she said. ``Those two kids are famous because they killed people, and that's not what this should be about.'' -=-=-
