U.S. & World

BLACKSBURG, Va. (CBS News) ― Long before he snapped, Virginia Tech gunman Cho Seung-Hui was picked on, pushed around and laughed at over his shyness and the strange way he talked when he was a schoolboy in the Washington suburbs, former classmates say.

Chris Davids, a Virginia Tech senior who graduated from Westfield High School in Chantilly, Va., with Cho in 2003, recalled that the South Korean immigrant almost never opened his mouth and would ignore attempts to strike up a conversation.

Once, in English class, the teacher had the students read aloud, and when it was Cho's turn, he just looked down in silence, Davids recalled. Finally, after the teacher threatened him with an F for participation, Cho started to read in a strange, deep voice that sounded "like he had something in his mouth," Davids said.

"As soon as he started reading, the whole class started laughing and pointing and saying, 'Go back to China,'" Davids said.

The high school classmates' accounts add to the psychological portrait that is beginning to take shape, and could shed light on Cho's state of mind in the video rant he mailed to NBC in the middle of his rampage Monday at Virginia Tech.

He shot 32 people to death and committed suicide in the deadliest one-man shooting rampage in modern U.S. history.

In the often-incoherent video, the 23-year-old Cho portrays himself as persecuted and rants about rich kids.

"Your Mercedes wasn't enough, you brats," says Cho, who came to the U.S. in 1992 and whose parents work at a dry cleaners in suburban Washington. "Your golden necklaces weren't enough, you snobs. Your trust funds wasn't enough. Your vodka and cognac wasn't enough. All your debaucheries weren't enough. Those weren't enough to fulfill your hedonistic needs. You had everything."

Among the victims of the massacre were two other Westfield High graduates: Reema Samaha and Erin Peterson. Both young women graduated from the high school last year. Police said it is not clear whether Cho singled them out.

Stephanie Roberts, 22, a fellow member of Cho's graduating class at Westfield High, said she never witnessed anyone picking on Cho in high school.

"I just remember he was a shy kid who didn't really want to talk to anybody," she said. "I guess a lot of people felt like maybe there was a language barrier."

But she said friends of hers who went to middle school with Cho told her they recalled him getting picked on there.

"There were just some people who were really mean to him and they would push him down and laugh at him," Roberts said Wednesday. "He didn't speak English really well and they would really make fun of him."

Virginia Tech student Alison Heck said a suitemate of hers on campus — Christina Lilick — found a mysterious question mark scrawled on the dry erase board on her door. Lilick went to the same high school as Cho, according to Lilick's Facebook page. Cho once scrawled a question mark on the sign-in sheet on the first day of a literature class, and other students came to know him as "the question mark kid."

"I don't know if she knew that it was him for sure," Heck said. "I do remember that that fall that she was being stalked and she had mentioned the question mark. And there was a question mark on her door."

Heck added: "She just let us know about it just in case there was a strange person walking around our suite."

Lilick could not immediately be located for comment, via e-mail or telephone.

On Wednesday, NBC received a package containing a rambling and often incoherent 23-page written statement from Cho, 28 video clips and 43 photos — many of them showing Cho brandishing handguns. A Postal Service time stamp reads 9:01 a.m. — between the two attacks on campus.

The package helped explain one mystery: where the gunman was and what he did during that two-hour window between the first burst of gunfire, at a high-rise dorm, and the second attack, at a classroom building.

"You had a hundred billion chances and ways to have avoided today," a snarling Cho says on video. "But you decided to spill my blood. You forced me into a corner and gave me only one option. The decision was yours. Now you have blood on your hands that will never wash off."

Col. Steve Flaherty, superintendent of the Virginia State Police, said Thursday that the material contained little they did not already know. Flaherty said he was disappointed that NBC decided to broadcast parts of it.

"I just hate that a lot of people not used to seeing that type of image had to see it," he said.

On NBC's "Today" show Thursday, host Meredith Vieira said the decision to air the information "was not taken lightly." Some victims' relatives canceled their plans to speak with NBC because they were upset over the airing of the images, she said.

"I saw his picture on TV, and when I did I just got chills," said Kristy Venning, a junior from Franklin County, Va. "There's really no words. It shows he put so much thought into this and I think it's sick."

Some of the pictures in the video package show him smiling; others show him frowning and snarling. Some depict him brandishing two weapons at a time, one in each hand. He wears a khaki-colored military-style vest, fingerless gloves, a black T-shirt, a backpack and a backward, black baseball cap. Another photo shows him swinging a hammer two-fisted. Another shows an angry-looking Cho holding a gun to his temple.

"What he has shown in this video is he's a psychopath," criminal profiler Pat Brown told CBS' The Early Show.

"He wasn't crazy, because he knew exactly what he was doing," Brown said.

Also, a search of Cho's dorm room and backpack produced eight pages of notes that law enforcement sources characterize as a "suicide note," reported CBS News correspondent Bob Orr.

Orr reported the writings found in Cho's dorm "appear to be a manifesto."

"He (Cho) just seemed to hate everybody," a law enforcement official said. The notes, he continued, "are page after page of single-spaced rantings."

This contradicts Tuesday's statement by the Virginia State Police that no suicide note was found.

Earlier in the day, authorities disclosed that more than a year before the massacre, Cho was accused of sending unwanted messages to two women and was taken to a psychiatric hospital on a magistrate's orders and was pronounced a danger to himself. But he was released with orders to undergo outpatient treatment.

The disclosure added to the rapidly growing list of warning signs that appeared well before the student opened fire. Among other things, Cho's twisted, violence-filled writings and sullen, vacant-eyed demeanor had disturbed professors and students so much that he was removed from one English class and was repeatedly urged to get counseling.

Some of the pictures in the video package show him smiling; others show him frowning and snarling. Some depict him brandishing two weapons at a time, one in each hand. He wears a khaki-colored military-style vest, fingerless gloves, a black T-shirt, a backpack and a backward, black baseball cap. Another photo shows him swinging a hammer two-fisted. Another shows an angry-looking Cho holding a gun to his temple.

He refers to "martyrs like Eric and Dylan" — a reference to the teenage killers in the Columbine High School massacre.

NBC News President Steve Capus said the package arrived in Tuesday afternoon's mail, but was not opened until Wednesday morning. It was sent by overnight delivery and apparently had the wrong ZIP code, NBC said.

An alert postal employee brought the package to NBC's attention after noticing the Blacksburg return address and a name similar to the words reportedly found scrawled in red ink on Cho's arm after the bloodbath, "Ismail Ax," NBC said.

Capus said that the network notified the FBI around noon, but held off reporting on it at the FBI's request, so that the bureau could look at it first. NBC finally broke the story just before police announced the development at 4:30 p.m.

It was clear Cho videotaped himself, Capus said, because he could be seen leaning in to shut off the camera.

State Police Spokeswoman Corinne Geller cautioned that, while the package was mailed between the two shootings, police have not inspected the footage and have yet to establish exactly when the images were made.

Cho repeatedly suggests he was picked on or otherwise hurt.

"You have vandalized my heart, raped my soul and torched my conscience," he says, apparently reading from his manifesto. "You thought it was one pathetic boy's life you were extinguishing. Thanks to you, I die like Jesus Christ, to inspire generations of the weak and the defenseless people."

A law enforcement official said Cho's letter also refers in the same sentence to President Bush and John Mark Karr, who falsely confessed last year to having killed child beauty queen JonBenet Ramsey. The official spoke on condition of anonymity because the person was not authorized to speak to the media.

Earlier Wednesday, authorities disclosed that in November and December 2005, two women complained to campus police that they had received calls and computer messages from Cho. But the women considered the messages "annoying," not threatening, and neither pressed charges, Virginia Tech Police Chief Wendell Flinchum said.

Neither woman was among the victims in the massacre, police said.

After the second complaint about Cho's behavior, the university obtained a temporary detention order and took Cho away because an acquaintance reported he might be suicidal, authorities said. Police did not identify the acquaintance.

On Dec. 13, 2005, a magistrate ordered Cho to undergo an evaluation at Carilion St. Albans, a private psychiatric hospital. The magistrate signed the order after an initial evaluation found probable cause that Cho was a danger to himself or others as a result of mental illness.

The next day, according to court records, doctors at Carilion conducted further examination and a special justice, Paul M. Barnett, approved outpatient treatment.

A medical examination conducted Dec. 14 reported that that Cho's "affect is flat. ... He denies suicidal ideations. He does not acknowledge symptoms of a thought disorder. His insight and judgment are normal."

The court papers indicate that Barnett checked a box that said Cho "presents an imminent danger to himself as a result of mental illness." Barnett did not check the box that would indicate a danger to others.

It is unclear how long Cho stayed at Carilion, though court papers indicate he was free to leave as of Dec. 14. Virginia Tech spokesman Larry Hincker said Cho had been continually enrolled at Tech and never took a leave of absence.

A spokesman for Carilion St. Albans would not comment.

Though the incidents with the two women did not result in criminal charges, police referred Cho to the university's disciplinary system, Flinchum said. But Ed Spencer, assistant vice president of student affairs, would not comment on any disciplinary proceedings, saying federal law protects students' medical privacy even after death.

Some students refused to second-guess the university.

"Who would've woken up in the morning and said, 'Maybe this student who's just troubled is really going to do something this horrific?"' said Elizabeth Hart, a communications major and a spokeswoman for the student government.

One of the first Virginia Tech officials to recognize Cho's problems was award-winning poet Nikki Giovanni, who kicked him out of her introduction to creative writing class in late 2005.

Students in Giovanni's class had told their professor that Cho was taking photographs of their legs and knees under the desks with his cell phone. Female students refused to come to class. She said she considered him "mean" and "a bully."

Lucinda Roy, professor of English at Virginia Tech, said that she, too, relayed her concerns to campus police and various other college units after Cho displayed antisocial behavior in her class and handed in disturbing writing assignments.

But she said authorities "hit a wall" in terms of what they could do "with a student on campus unless he'd made a very overt threat to himself or others." Cho resisted her repeated suggestion that he undergo counseling, Roy said.

Questions lingered over whether campus police should have issued an immediate campus-wide warning of a killer on the loose and locked down the campus after the first burst of gunfire.

Police said that after the first shooting, in which two students were killed, they believed that it was a domestic dispute, and that the gunman had fled the campus. Police went looking for a young man, Karl David Thornhill, who had once shot guns at a firing range with the roommate of one of the victims. But police said Thornhill is no longer under suspicion.

In other developments:

•   Cho Seung-Hui had troubled his parents as a child because of speech difficulties, a South Korean newspaper reported Thursday. Cho left South Korea with his family in 1992 to seek a better life in the United States, Cho's grandfather told the Dong-a Ilbo daily. The 81-year-old grandfather identified only as Kim said Cho "troubled his parents a lot when he was young because he couldn't speak well, but was well-behaved," the report said.

•   Virginia Tech got another scare Wednesday morning as police in SWAT gear with weapons drawn swarmed Burruss Hall, which houses the president's office. The threat targeted the university president but was unfounded and the building was reopened, said police chief Flinchum.

•   Virginia Tech police chased a fruitless lead in the early-morning murders of two students at a dorm, halting officials from sending out a warning about a possible gunman on the loose, according to police statements reported by The New York Times.
