Blanning also left notes demanding cash and saying "Aspen will pay a horrible price in blood" if his demands were not met. The typewritten notes said he was targeting four banks, police said, but only two
-- a Wells Fargo Bank and a nearby Vectra Bank -- received the packages.
Later, police found two similar packages atop a black sled in a downtown alley. Blanning sent a copy of the notes to The Aspen Times newspaper.
"We believe the suspect abandoned his plan halfway through," said Assistant Aspen Police Chief Bill Linn.
Police found Blanning dead in his Jeep Cherokee a few hours later in a rural area east of Aspen. In his Jeep, they found a rifle and a handgun that Linn says Blanning used to kill himself.
Blanning's bombs caused the evacuation a 16-block area -- nearly all of downtown Aspen. The evacuation lasted until 4 a.m., meaning the resort's hallmark mountaintop firework display and ritzy downtown parties were canceled.
Aspen restaurants and high-end stores tried to recapture the holiday spirit Thursday night with a rescheduled fireworks display. Revelers even started chanting a New Year's Eve-style countdown. But the party numbered in the hundreds, not the thousands.
"It hurt us bad," said Peter Calamari, an art gallery owner who said New Year's Eve is typically one of his top-selling evenings. "We had to close three galleries."
Bartenders and waiters, often young people who come to Aspen to work just during skiing season, grumbled they would not make up their lost holiday pay.
"Usually, it's a madhouse in here -- everybody's making money, everybody's having fun" on New Year's Eve, said Chip Blake, manager of Bad Billy's bar in downtown Aspen. "I had 10 people last night out of work."
There were plenty of women wearing ankle-length fur coats with designer boots Thursday night but it was no match for a typical holiday here.
"We just stayed home and had a bottle of wine and some crackers," said Aspen resident Rick Peckham. Peckham returned downtown to see the rescheduled fireworks with some friends visiting for New Year's, but their second take at ringing in 2009 wasn't much fancier
-- just some homemade spaghetti before watching the fireworks.
Blanning's note said a fifth bomb was "hidden in a high-end watering hole." Linn said Aspen bars were searched early Thursday but that no additional bomb was discovered.
The bombs were detonated before dawn. One caused a fireball, but no one was hurt, Linn said.
Police had released Blanning's name and picture before finding his body. Authorities recognized him on a surveillance tape from one of the banks, wearing a ski cap and dark glasses.
