The Skinny is Joel Roberts' take on the top news of the day and the best of the Internet.
Among the countless heartrending stories to emerge from the Virginia Tech rampage, one of the most poignant is that of Liviu Librescu, an Israeli professor and Holocaust survivor who died while saving the lives of his students.
Librescu, a 76-year-old professor of aerospace engineering, barricaded the door to his classroom, blocking the shooter from entering and giving his students time to escape out the window.
"He saved my life," one student told the Los Angeles Times.
In a case of tragic irony, USA Today points out that Librescu was killed "shielding his students from a mass murderer on the day that Jews who were mass murdered during World War II are remembered each year."
Librescu's son, Joe, said his father's death on Holocaust Remembrance Day was "symbolic."
"This was typical of him. He did not fear death and at all times tried to do the right thing."
Gunman A Mystery Even To Roommates
He's been widely described as a "loner" with few friends, but even his roommates say they knew little about Cho Seung-Hui.
Two students who shared a suite with Cho at Virginia Tech's Harper Hall describe him as a virtual stranger, who ate his meals alone in the dining hall and rebuffed any attempts at friendship.
"He was my roommate," 19-year-old sophomore Joe Aust told the New York Times. "I didn't know him that well, though."
Aust and another suitemate, Karan Grewal, 21, said they never saw Cho with a girl or with any friends.
But while they thought he was strange, they never imagined he was capable of mass murder.
"He was always really, really quiet and kind of weird, keeping to himself all the time," Aust said. "Just anti-social, didn't talk to anybody."
Grewal told the Washington Post that Cho began the day Monday just as he did every other day.
"He didn't have a look of disgust or anger. He never did. There was always just one look on his face," Grewal said.
"He had that blank expression, nothing else."
