There were three men on board the plane, all Mexican natioonals. One was killed, one suffered a serious injury, and the other suffered what appeared to be a minor injury, the Pitkin County Sheriff's Office told CBS News.
Alex Burchetta, director of operations for the Pitkin County Sheriff's Office, identified the man who died as Sergio Carranza Brabata. He did not release the names of the two injured and he did not know where in Mexico Brabata lived.
A Federal Aviation Administration spokesman initially said the plane appeared to be a Bombadier Challenger 600. But Peter Knudson, a spokesman for the National Transportation Safety Board, said the plane was a Canadair CL-600, a midsized private jet.
The aircraft was registered to the Bank of Utah in Salt Lake City, according to FAA records.
The fight originated in Mexico and was continuing on from Tucson, Ariz., to Aspen when the crash occurred at 12:22 p.m. local time, said FAA spokesman Allen Kenitzer.
Airport officials said the facility would be closed until further notice.
Actor and comedian Kevin Nealon tweeted that he witnessed the crash. He called it “horrible," and said it "didn't look like there could be survivors but just hearing some survived but critical."
Country singer LeAnn Rimes also said she saw the crash. "So sad! Horrible plane crash we just saw happen at the Aspen airport," she tweeted.
Aspen, nestled in the Rocky Mountains and home to several ski upscale resorts, is about 100 miles southwest of Denver.Tom Renwick, a National Weather Service meteorologist in Grand Junction, Colo., said there were snow showers in the area on Sunday afternoon, but not at the airport. He said it had been overcast all day with temperatures hovering around 10 degrees.
