An Arizona man is facing a manslaughter charge in connection with a collision that killed the sister of former U.S. Supreme Court Justice Sandra Day O'Connor.

Pima County Sheriff's officials in Tucson said Sunday that 24-year-old Jarrad Barnes has been booked on one count each of manslaughter and driving under the influence.

Barnes was arrested immediately after being released Saturday night from a hospital for injuries that were not life-threatening.

The sheriff's office did not know if he had an attorney.

Authorities say 77-year-old Ann Day was driving Saturday morning when Barnes' vehicle crossed the median and struck her car head-on.

The collision also led to a truck rear-ending Day's car. That driver also was hospitalized for injuries that were not life-threatening.

Day also is a former Republican state senator and Pima County supervisor.
