Gunman sent video and photos to NBC

In the video, he makes reference to the shooters at Columbine High School.
BLACKSBURG, Va. (AP) -- 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."
NBC said the package contained a rambling and often-incoherent, 1,800-word video manifesto on CD, plus 43 photos, 11 of them showing him aiming handguns at the camera.
The package arrived at NBC headquarters in New York on Tuesday and was opened 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.
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 massacre.
Warning signs
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.
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.
