Reema Samaha

Reema Samaha, 18, a freshman from Centreville, Va., was shot and killed in her French class. According to tributes posted by friends online, she was an avid dancer and actor who devoted much of her time to the school's Contemporary Dance Ensemble, a student organization. As a high school student, she won awards for her performances, including one for her role in "Fiddler on the Roof."

Nicole Bonfiglio, a fellow student at Virginia Tech, remembered Reema in a tribute on the website Facebook as "one of my first friends in high school," adding, "We sat next to each other in bio freshman year. Reema...you were so kind...you were one of the kindest people i met that year and throughout high school. Nobody ever had anything but good things to say about you."

Her brother, Omar Samaha, told MSNBC: "I couldn't sleep last night. Every time I was trying to fall asleep, more things would pop into my head.

"I know I'll get through it," he added, "and I'm going to pray for everyone else."

Very accomplished dancer. Her father says on CNN news: "She found her niche at the university... major in international relations... she wanted to solve the problems of the world"
