PHOENIX - The Yavapai County Attorney's Office will be taking over the investigation into a fatal crash in Tempe involving a self-driving Uber after the Maricopa County Attorney's Office determined a potential conflict of interest.

According to a release from Maricopa County Attorney Bill Montgomery, the office was investigating Tempe police reports detailing the crash that killed a pedestrian attempting to cross Mill Avenue in March when it conducted a conflict of interest review.

The potential conflict of interest stems from a previous partnership between the county attorney's office and Uber during the 2016 "Save Lives, Don't DUI" campaign, when MCAO encouraged the public to use the ride-sharing service to avoid drinking and driving.

The county attorney's office said it actively promoted the service with discounts during the campaign.

The release went on to say that there is no known connection between MCAO and the Uber self-driving tests that were being conducted in Tempe.

Yavapai County Attorney Sheila Polk agreed to accept and review the case.
