The disturbing video of an armed Cho Seung-Hui delivering a snarling tirade about rich "brats" and their "hedonistic needs" had some marginal value to the official investigation, but it didn't add much that police didn't already know, State Police said Thursday

The self-made video and photos of Cho pointing guns as if he were imitating a movie poster were mailed to NBC on the morning of the Virginia Tech massacre. A Postal Service time stamp reads 9:01 a.m. — between the two attacks that left 33 people dead.

"This is it. This is where it all ends," Cho says in one videotape, in which he appears to be more melancholy than angry. "What a life it was. Some life."

Cho, 23, speaks in a harsh monotone in other videotaped rants, but it isn't clear to whom he is speaking. Some of his photos resemble scenes from a South Korean movie in Chan-wook Park's "Vengeance Trilogy."

"You had a hundred billion chances and ways to have avoided today," Cho says in one, with a snarl on his lips. "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. It was given to State Police but contained little that they didn't already know, Col. Steve Flaherty 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."

The package helped 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 attack, 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."

There has been some speculation, especially among online forums, that Cho may have been inspired by the South Korean movie "Oldboy." One of the killer's mailed photos shows him brandishing a hammer — the signature weapon of the protagonist — and in a pose similar to one from the film.
