Blacksburg, Va. ? Midway through his murderous rampage, the Virginia Tech gunman went to the post office and mailed NBC a package containing photos and videos of him brandishing guns and delivering a snarling, profanity-laced tirade about rich “brats” and their “hedonistic needs.”

Blacksburg, Va., customers watch the NBC Nightly News as they dine in a local restaurant. Between his first and second bursts of gunfire, Virginia Tech gunman Cho Seung-Hui mailed a package to NBC that containing photos of him brandishing guns and video of him delivering an angry, profanity-laced tirade.

“You had a hundred billion chances and ways to have avoided today,” 23-year-old Cho Seung-Hui says in a harsh monotone. “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.”

NBC said the package contained a rambling and often incoherent 23-page written statement, 28 video clips and 43 photos. Several of the photos showed him aiming handguns at the camera.

The package arrived at NBC headquarters in New York Wednesday, two days after Cho killed 32 people and committed suicide in the deadliest one-man shooting rampage in modern U.S. history. It bore a Postal Service time stamp showing that it had been mailed at a Blacksburg post office at 9:01 a.m. Monday, about an hour and 45 minutes after Cho first opened fire.

That would help explain one of the biggest mysteries about the massacre: 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 fusillade, at a classroom building.

“Your Mercedes wasn’t enough, you brats,” says Cho, a South Korean immigrant 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.”

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. One 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 massacre.

NBC News said the package arrived in New York late Tuesday night and was delivered to the network’s headquarters about 11 a.m. Wednesday. 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.

Comparison to Jesus

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.

‘Annoying’ women

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.

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.

Kicked out of class

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 campuswide 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.

Day of mourning

Also Wednesday, Virginia Gov. Timothy M. Kaine declared Friday a statewide day of mourning, and asked the state to pause at noon to pray for the victims. Montgomery County Public Schools also said they would remain closed for the rest of the week.

With classes canceled through the week, the Virginia Tech campus continued to empty Wednesday. But students from other schools came to pay their respects, visiting the makeshift shrines of candles, flowers and placards – all thick with prayers and condolences.
