St. Joseph’s Medical Center in Arizona mixed up the identities of two women involved in a car crash last week, says CNN, leading to some intensely unpleasant fake-outs for both families involved.

Hospital officials say they didn’t have enough identifying information on the women when they were brought in, so they asked family members for information they could use to determine identity. Based on that, they assigned names to bodies. Later, the medical examiner looked at dental records and realized they’d made a mistake.
