Huff killed six people and then himself during a house party last March.
Police are releasing this letter to the public after numerous media requests. It was found in a dumpster in April -- nearly a month after the murders. They still don't know if this letter is real, but if it is, it appears to shed light on one of Seattle's worst mass killings.
The one page, hand written letter is addressed to Kyle Huff's twin brother Kane. It's dated two days before the mass killings.
It begins, "I hope that you'll find this letter after the fact."
Ever since the killings last March, investigators have been searching for a motive.
"This could be a key component in determining at least part of his mindset if it's authenticated," said Officer Deanna Nolette with Seattle Police.
The killings took place after Huff attended a rave with many of the victims. The note appears to express anger toward the rave culture.
The writer refers to the ravers as "hippies" and questions their morals.
"I hate this world of sex that they're striving to make," the letter continues. "The things they say and do are just too disturbing to me to just ignore...
"The basic jist (sic) of it is that they're (having sex) next to us when we're really high to make us freak out."
The letter was found a month after the shootings miles from the killer's house.
Police are a bit skeptical about how and where the letter was found. It was discovered by an apartment manager who was rifling through this recycling bin trying to figure out who was dumping illegal garbage there.
But police say there is at least one sign that Huff is the author. The note is written on the back of a memo to tenants of the Town & Country Apartment's -- where Huff lived. A crime lab is still analyzing the handwriting to see if it is Huffs.
"I think that the families are looking for some sort of answer as to why this happened and maybe we can provide some small piece of information as to what was going on," Nolette said.
And maybe, police say, if they can understand this killer - they can prevent this from happening again.
