Authorities have identified a woman killed in a fatal crash in the lower valley last Thursday. Yakima County Sheriff's deputies say 34-year-old Caroline Pacheco was driving a Chevrolet Traverse north on South Wapato Road at about 8:15 a.m. They say she had the right-of-way when her car collided with a semi-truck traveling west on Progressive road that authorities say failed to stop at the stop sign. Pacheco died in the crash. Her 6-year-old son was in the back seat and was treated and released from a local hospital. The 44-year-old truck driver was not injured. The crash remains under investigation.
