John Denver's body was cremated Wednesday, as federal investigators packed up and prepared to leave the site of the singer's fatal airplane crash.
National Transportation Safety Board investigators were to return to their offices in Los Angeles and Washington to complete their work after finishing up a few remaining details at the site of Sunday's crash.
With a backlog of cases, it could take six months to determine the cause of the crash, NTSB spokesman Matt Furman said.
"There are approximately 2,000 aviation accidents in this country every year and the NTSB by law has to investigate all of them. This one goes into the pipeline," he said.
The ashes of the singer were to be taken by two friends to Colorado, where two memorial services are scheduled, said Denver's publicist Paul Shefrin.
A private service is scheduled for Friday morning at a church in Aurora, Colo., a Denver suburb, and a public service is scheduled for Saturday afternoon in Aspen.
"We were trying to keep one (private), but it didn't work out," Shefrin said. "That's why the Aspen one went public."
