SEATTLE – The man who shot and killed six people inside a Capitol Hill home in March 2006 apparently left behind a letter that shows how deep his anger was.

Kyle Huff

Sources told KING 5 police believe the letter was written by Kyle Huff to his identical twin brother Kane. It was turned over to police by someone completely unconnected to the crime, and in it Huff vents his rage at the rave culture.

From their hiding places, they called for help as the heavily armed shooter strolled through the Capitol Hill house gunning down victims at an early morning party.

As the bodies were brought out, one by one, friends, relatives and neighbors wondered why.

The only clue was the word “now” that killer Kyle Huff spray-painted near the house.

Huff’s only connection to the six victims was coincidental. He had met them at a late-night rave and was invited to join them at an after-hours party.

Huff came heavily armed and on a mission, but until now we have not known what that was.

Sources say that a suicide note, written to his twin brother, was found, dated several days before the shooting. In it, Kyle criticized the rave scene.

The souce said Kyle wrote about people packed together, groping each other and having sex.

Why did it take so long for the letter to surface?

It was only found recently along with the makings of a bomb inside a dumpster not far from the apartment where Huff and his brother lived.

SPD’s bomb squad blew up the device and took the letter in for analysis.

KING 5 was told that police had matched the letter to Kyle Huff’s handwriting and that it was meant to be found after he had completed his gruesome task. Sources said that in the letter Huff expressed regret that he will never see Kane again but tells him he will be part of him as long as Kane is alive.

He urges Kane not to show the letter to police or the FBI.

The letter had not yet turned up when Police Chief Gil Kerlikowske announced that he was assembling a national panel to get answers to one of the worst mass killings in Seattle’s history.

"There are lots of people with lots of different theories, that's why this panel of experts, multidisciplinary people who have got great expertise, are going to help guide this investigation,” said Kerlikowske.

The letter finally offers an explanation and, KING 5 has also learned, the toxicology report is complete. Only alcohol was found in Huff’s system – no Ecstasy or other drugs.

As for that one mysterious clue left on a sidewalk, the letter appears to have an answer. According to our source, it was Huff’s final declaration that he was taking action against the raves he despised and that he felt the need to act immediately.

How the letter turned up in a dumpster more than a month after the massacre remains a mystery. The apartment owner discovered it accidentally as he was digging through the trash looking for clues to find out who was illegally using his dumpster.

Do police believe that Kyle’s brother Kane put it there?

KING 5’s source said police do not know who put it there, but police believe Kane did not see the letter before the shootings. In fact, we were told, he denies ever seeing it at all.

As for the bomb materials, it raises question about whether Kyle Huff might have had a different plan at one point.

Chief Kerlikowske has not commented on the letter. He said he hopes to unveil his panel's full report by the end of May.
