Memorial service for 3 fallen firefighters Sunday at 1 p.m.

WENATCHEE, Wash. -- A service for the three firefighters who died while battling the Okanogan complex of wildfires last week will be held at 1 p.m. Sunday at the Toyota Center in Wenatchee.

The memorial service for 20-year-old Tom Zbyszewski, 26-year-old Andrew Zajac, and 31-year-old Richard Wheeler will be held about 90 miles south of where they died last week in Twisp.

Officials said the three died when their truck crashed down a 40-foot embankment as they tried to escape the fast-growing wildfire and flames consumed their vehicle. All three lived in north-central Washington.

Another firefighter, 25-year-old Daniel Lyon, was upgraded to serious condition on Saturday after sustaining burns over 60 percent of his body.

Lyon was one of four firefighters injured when flames overtook them on Aug. 19. The other three injured firefighters have been treated and released.

Meanwhile, The National Fallen Firefighters Foundation has set up the Twisp River Fallen Firefighters Fund to help honor the three Okanogan-area firefighters who died.

Money donated to the fund will go to help the families, friends and colleagues of the men who died trying to protect this state. Money will also go to the survivors of the blaze, as they could need help for years to come.

Donated funds will be used to help the survivors and coworkers as they begin to rebuild their lives and support the programs and services they will need, promised Chief Ronald Siarnicki, executive director of the National Fallen Firefighters Foundation.
