For reasons that aren’t yet clear, an SUV veered from a busy DeKalb County road Saturday, striking a mailbox and plowing into a fence as a woman was ejected and killed.

Officers found Nicole Tibbs, 42, of Atlanta in the grass near a house at 4666 Lawrenceville Highway around 3:15 a.m., a police report said. She had been a passenger in the Chevrolet Tahoe traveling through Tucker; the driver and another passenger, both adults, were trapped under the Tahoe, which flipped after hitting the fence.

The people under the SUV were alert and transported to Grady Memorial Hospital in critical condition, the report said. Their condition wasn’t known Monday afternoon.

Tibbs was dead when police arrived.
