A firefighter severely injured in a wildfire flare-up that killed three of his comrades in eastern Washington state has left the hospital after three months of treatment.

But Daniel Lyon's recovery is far from complete. The 25-year-old who suffered burns to more than 60 percent of his body on Aug. 19 still hasn't regained use of his hands.

Lyon said at a news conference Wednesday that the hardest part of his recovery has been mental, not physical. He says he thinks every day about his friends who died in the blaze near Twisp: 20-year-old Tom Zbyszewski, 26-year-old Andrew Zajac and 31-year-old Richard Wheeler.

The fast-moving fire overtook their vehicle after it crashed down an embankment.

Lyon has spent the past three months at Harborview Medical Center in Seattle.
