BAKER CITY -- Survivors of a van crash on an icy Oregon freeway that killed two young people from Colorado say they're trying to come to grips with their loss.

Eighteen-year-old Sarah DeVries tells The Baker City Herald that she's still "waiting for this to be a dream."

Joshua John Pischura died shortly after the crash late Thursday on Interstate 84 near Baker City, about 130 miles northwest of Boise. Taune Nicole Winter Pepper died after being flown to a Boise hospital. Two passengers listed in critical condition are identified as Aaron Stearling Werntz and Phillip Joel Harris.

They were among 16 young men and women from the New Life Worship Center in suburban Denver traveling to Portland when their van slid on black ice and rolled several times, ejecting most of them.

Oregon State Police said Friday it may be several weeks before investigators complete their report on the crash.
