(PENDLETON, Ore.) -- Police in Oregon are just now beginning what they say will be a month-long investigation into a fatal bus crash last Sunday near Pendleton in eastern Oregon, which killed nine people and injured 49 others.
Police say they won't know until the investigation is complete if charges will be filed against the driver.
The bus crashed in an icy patch of highway and rolled down an embankment. Lt. Gregg Hastings with the Oregon State Police said the bus "veered across both westbound lanes, struck a guardrail, continued through the guardrail down about 200 feet to where it came to rest."
"Many of the occupants were ejected or partially ejected from the bus. There obviously were many people injured still inside the bus," Hastings said in a Monday press conference. He noted that the area's conditions were "slippery" and that Sunday's bus crash was the second of two fatal crashes that morning.
"We had another one a few hours earlier," Hastings said.
Lt. Hastings said he expects the investigation into what caused the crash to "last up to four weeks, possibly longer."
