ASPEN, Colo. (AP) -- The death of snowmobile rider Caleb Moore and another accident involving a driver-less snowmobile that careened into a fence and injured a spectator at the Winter X Games will trigger a more thorough review of the permit process for next year's event.

On Thursday, Moore died from injuries suffered when he flew off his snowmobile and it rolled over him while he was attempting a backflip.

Mike Kraemer, a planner for the department that handles special event permits in Aspen, said Friday that ESPN's permit will be reviewed before next year's Winter X Games, as it is every year.

Kraemer said public safety is the department's first priority, and though it doesn't regulate course design or the sport itself, that could be brought into the discussion during the permitting process.

The review was first reported by The Aspen Times.
