A 24-year-old Arizona man has been charged with manslaughter in the fatal car accident that killed the younger sister of former Supreme Court Justice Sandra Day O'Connor.
Jarrad Barnes also faces one count of driving under the influence, the Pima County Sheriff's Office said in a statement Sunday.
Ann Day, 77, was a former Pima County supervisor and state senator. Her sister, the first woman on the Supreme Court, retired in 2006.
She was driving in the Tucson area Saturday morning when Barnes, who was driving a vehicle in oncoming traffic, crossed a median and struck Day head-on, authorities said. Day's car was then rear-ended by a truck.
Day was pronounced dead at a hospital.
Barnes, who was also been examined for non-life-threatening injuries, was released from the hospital Saturday night and immediately booked into the Pima County jail, the statement said.
