OTHELLO, Wash. -- A 20-year old Othello woman is dead after a rollover accident. It happened Monday afternoon just after 4:30 outside of Othello near Hatton Road and Linda Lane. Adams County sheriff's deputies report 20-year old Brittney Almaguer and two 17-year old girls were seen shooting off fireworks near a wheat field, but they took off at a high rate of speed when the landowner approached them.

Almaguer was not wearing a seatbelt and was ejected from her vehicle. Emergency works and a Medstar helicopter arrived, but Almaguer died at the scene. The two 17-year old girls were both wearing seatbelts. They were taken to Othello Community Hospital where they were treated and released. Investigators found fireworks, alcohol and marijuana in the car. The Adams County Coroner will determine if an autopsy will be performed.
