No Warnings On Seattle Shooter

The man suspected of killing six people at an after-rave house party lived with his twin brother and delivered pizzas since he moved to Seattle, where his apartment manager said the two were ideal tenants and "twin teddy bears."

Those who knew Aaron Kyle Huff were dismayed that he was suspected of opening fire in a house full of partygoers dressed like zombies in dark clothing and pale makeup, killing six of them and injuring two. He then turned the gun on himself, authorities said.

"It's a total shock," said Regina Gray, manager of Town & Country Apartments, where the Huff brothers lived. "He and his twin brother are the kindest, sweetest, gentlest people."

It was a sharp contrast to the man police spokesman Sean Whitcomb described Sunday as "extremely dangerous" who "approached the house shooting and didn't stop shooting."

Police say the victims met Huff, 28, at a rave called "Better Off Undead" Friday night and invited him back to an after-party at their rental home in the Capitol Hill neighborhood.

The capitol Hill neighborhood is described as an eclectic young neighborhood going through a regentrification process, reports CBS News correspondent Vince Gonzales. The partygoers were described as all good friends and the suspect was one of the guests.

Some 500 people attended the rave — parties that attract young people to dance to thumping, bass-laden electronic music. People often dress up in Halloween-like outfits and paint their faces.

"She shouldn't have gone to the rave and I never approved of those things," the mother of a woman at the party told CBS News. "But it's kind of like, tell them no and they go anyway. I would rather know."

Huff left the after-party at about 7 a.m. and returned wearing bandoliers of ammunition and carrying a 12-gauge pistol-grip shotgun and a handgun. He fired on the 30 young partygoers gathered in the house before walking out and killing himself when confronted by a police officer.

"Almost immediately upon coming right back to the house, he opened fire on people outside the residence," said Police Chief Gil Kerilowske. "The people inside the house began running and screaming in terror."

Police also found an assault rifle, multiple "banana clips" carrying 30 bullets each, a machete and several hundred more rounds of ammunition in Huff's pickup truck. Police say they are still working on a motive.

"He left the party and made no threatening gestures. There was no argument, there were no fights," said Kerlikowske. "He was in fact described as quiet and humble."

"This would have been so far out of character," said Jim Pickett, the assistant manager of the Town & Country Apartments.

Pickett described the brothers as "very polite. Very respectful. 'Yessir. Yes ma'am. Can I help ya. How am I doing today?' ... You don't find two boys as respectful as these two always were."

The brothers moved into the third-floor apartment 4½ years ago after leaving their family home in Whitefish, Montana, apartment managers said. Police officials say Huff was commonly known as Kyle.

Pickett said he never saw either of the brothers with weapons, but he said he did see police carry three rifles out of the apartment after they searched it Saturday.

Pickett said he saw Huff's brother as police were conducting the search.

"He gave a look to me like 'I don't know what's going on,'" Pickett said.

Lt. Dave Leib, of the Flathead County sheriff's office in Montana, confirmed Huff's identity Sunday afternoon. He informed Huff's mother Sunday afternoon that her son was dead and was a suspect in the shootings.

Seattle officials did not release the gunman's identity Sunday, saying only the medical examiner could give an official confirmation on Monday.

Leib said Huff was charged with felony criminal mischief in 2000 after shooting a statue of a moose with a shotgun at an art exhibit in Whitefish.

Pickett described the brothers as private and good tenants. One of the brothers played drums, but was very careful not to disturb neighbors.

"He was really getting pretty good. He would practice at a respectful hour between 4 and 6 and would stop at 6," Pickett said.

Kyle Huff delivered pizzas in the area and did odd jobs, Gray said. She added that he would go home to Montana to do some work for his mother from time to time.

Authorities have not released the victim's identities, but relatives and friends of three victims, Jason Travers, 32, Jeremy Martin, 26, and Christopher Williamson, 21, confirmed that they were among the dead.

Several ravers gathered at a makeshift memorial near the crime scene Sunday morning, including Travis Webb, an area rave promoter who attended the rave that preceded the fatal party.

Webb said he and other ravers are fearful that officials would use the shooting as an excuse to shut down the parties. Police said alcohol and marijuana were found at the murder scene, but they had not linked them to the crime.

"It's almost a double punishment," Webb said. "You lose six people that are so close, and then you might lose the community that brought you all together in the first place."
