Two years ago, a gunman ended the lives of 32 students and faculty at Virginia Tech. We recall some of the victims below and remember all of the vibrant lives that were senselessly lost on that day.
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."

Clark, 22, was from Martinez, Georgia, just outside Augusta. He was a fifth-year student working toward degrees in biology and English, and a member of the Marching Virginians band.
"He was just one of the greatest people you could possibly know," friend Gregory Walton, 25, said after learning from an ambulance driver that Clark was among the dead.
"He was always smiling, always laughing. I don't think I ever saw him mad in the five years I knew him."

"She was just one of the most outstanding young individuals that I've had the privilege of working with in my 31 years as an educator," said John P. Latini, principal of Minisink Valley High School, where she graduated in 2005. "Caitlin was a leader among our students."
Minisink Valley students and teachers shared their grief Tuesday at a counseling center set up in the school, Latini said.
Perez Cueva was a student of international relations, according to the Virginia Tech Web site.
His father, Flavio Perez, spoke of the death earlier to RPP radio in Peru. He lives in Peru and said he was trying to obtain a humanitarian visa from the U.S. consulate here. He is separated from Cueva, who said she had lived in the United States for six years.
A spokesman at the U.S. Embassy in Lima said the student's father "will receive all the attention possible when he applies" for the visa.
Friend Steve Craveiro described him as smart, responsible and a hard worker, someone who never got into trouble.
"He would come home from school over the summer and talk about projects, about building bridges and stuff like that," Craveiro said. "He loved his family. He was pretty much destined to be extremely successful. He just didn't deserve to have happen what happened."
O'Neil graduated in 2002 from Lincoln High School in Rhode Island and graduated from Lafayette College in Easton, Pa., before heading to Virginia Tech, where he was also a teaching assistant, Craveiro said.

Bishop decided which German-language students at Virginia Tech could attend the Darmstadt University of Technology to improve their German.
"He would teach them German in Blacksburg, and he would decide which students were able to study" abroad, Darmstadt spokesman Lars Rosumek said.
The school set up a book of condolences for students, staff and faculty to sign, along with information about the Virginia shootings.
"Of course many persons knew him personally and are deeply, deeply shocked about his death," Rosumek said.
Bishop earned bachelor's and master's degrees in German and was a Fulbright scholar at Christian-Albrechts University in Kiel, Germany.
According to his Web site, Bishop spent four years living in Germany, where he "spent most of his time learning the language, teaching English, drinking large quantities of wheat beer, and wooing a certain fraulein."
The "fraulein" was Bishop's wife, Stephanie Hofer, who also teaches in Virginia Tech's German program.

Librescu taught at Virginia Tech for 20 years and had an international reputation for his work in aeronautical engineering.
"His research has enabled better aircraft, superior composite materials, and more robust aerospace structures," said Ishwar K. Puri, the head of the engineering science and mechanics department.
After surviving the Nazi killings, Librescu escaped from Communist Romania and made his way to the United States before he was killed in Monday's massacre, which coincided with Israel's Holocaust Remembrance Day.
Librescu's son, Joe, said his father's students sent e-mails detailing how the professor saved their lives by blocking the doorway of his classroom from the approaching gunman before Librescu was fatally shot.
"My father blocked the doorway with his body and asked the students to flee," Librescu's son, Joe Librescu, said Tuesday in a telephone interview from his home outside of Tel Aviv. "Students started opening windows and jumping out."

The head of the school's engineering science and mechanics department called Granata one of the top five biomechanics researchers in the country working on movement dynamics in cerebral palsy.
"With so many research projects and graduate students, he still found time to spend with his family, and he coached his children in many sports and extracurricular activities," said engineering professor Demetri P. Telionis. "He was a wonderful family man. We will all miss him dearly."
Granata was known worldwide for his research into how muscles accomplish complicated movements, said Stefan Duma, another engineering professor.
"He liked to ask the big questions," Duma said. "When we had students defending their Ph.D., and he kept asking, 'Did we have the total solution?' He was really interested in whether we answered the big questions. That's really a sign of a great scientist."

"We're mourning," Nowak said, declining to say more.
Couture-Nowak lived in Truro, Nova Scotia, in the 1990s where her husband was a plant science professor. She was instrumental in the push to create the town's first French school in 1997.
"She was a founding parent of one of our schools," said Richard Landry, a spokesman with the francophone school board in the province. "There were three mothers who worked hard to get the school and she was one of them."
Landry said she had two girls.
Couture-Nowak obtained her teacher's degree at the teacher's college in Truro in '88/'89, Landry said. After that she taught at a community college in early childhood development. She was also substitute teacher.
A posting on a Virginia Tech web site dedicated to rating teachers described Couture-Nowak as "an excellent teacher" who "is extremely nice and understanding."
His high school put up a memorial to Lane that included pictures, musical instruments and his athletic jerseys.
Lane played the trombone, ran track, and played football and basketball at Narrows High School. "We're just kind of binding together as a family," Principal Robert Stump said.
Lane's brother-in-law Daniel Farrell called Lane fun-loving and "full of spirit."
"He had a caring heart and was a friend to everyone he met," Farrell said. "We are leaning on God's grace in these trying hours."
Loganathan, 51, won several awards for excellence in teaching, had served on the faculty senate and was an adviser to about 75 undergraduate students.
"We all feel like we have had an electric shock. We do not know what to do," his brother G.V. Palanivel told the NDTV news channel from the southern Indian state of Tamil Nadu. "He has been a driving force for all of us, the guiding force."

"She worked at a veterinarian's office and cared about them her whole life," said Rappahannock County Administrator John W. McCarthy, a family friend.
Hilscher, 19, of Woodville, was a freshman majoring in animal and poultry sciences. She lived on the same dorm floor as victim Ryan Clark, McCarthy said.
A friend, Will Nachless, also 19, said Hilscher "was always very friendly. Before I even knew her, I thought she was very outgoing, friendly and helpful, and she was great in chemistry."
