Bus Crash on I-84

PORTLAND, Ore. (AP) -- A prosecutor says he has yet to decide whether to file criminal charges in connection with a fatal bus crash on Interstate 84 in Eastern Oregon.

In an interview with the Associated Press, Umatilla County District Attorney Dan Primus called the case "very complex" and said he has not convened a grand jury.

Nine people died and almost 40 were injured Dec. 30 when a bus carrying tourists smashed through a guardrail east of Pendleton and rolled down a hill.

The U.S. government quickly banned Mi Joo Tour & Travel from operating buses on U.S. roads. Federal officials found the driver was on duty for 92 hours in the eight-day stretch before the crash, exceeding federal limits.

Attorneys for the Canadian company said black ice -- not driver fatigue or excessive speed -- caused the crash.
