Authorities says a power line fell on a car in Portland, Oregon, killing three people and injuring a baby during an ice storm that turned roads and mountain highways treacherous in the Pacific Northwest. In a statement, the fire department said a large branch fell on the power line, causing it to crash down onto the car. Authorities say they believe the victims were electrocuted after they got out of the vehicle. Swaths of southwest Washington and northwest Oregon were under warnings earlier Wednesday for as much as an inch of ice. The National Weather Service said freezing rain could possibly return to the region Thursday and Friday.
