Ross Abdallah Alameddine

Alameddine was a sophomore who had just declared English as his major. Friends created a memorial page on Facebook.com that described Alameddine as "an intelligent, funny, easygoing guy."

"You're such an amazing kid, Ross," wrote Zach Allen, who along with Alameddine attended Austin Preparatory School in Reading, Mass. "You always made me smile, and you always knew the right thing to do or say to cheer anyone up."

Alameddine was killed in the classroom building, according to Robert Palumbo, a family friend who answered the phone at the Alameddine residence Tuesday. Alameddine's mother, Lynnette Alameddine, said she was outraged by how victims' relatives were notified of the shooting. "It happened in the morning and I did not hear [about her son's death] until a quarter to 11 at night," she said. "That was outrageous. Two kids died, and then they shoot a whole bunch of them, including my son."
