A woman trying to stop a motorist from fleeing after a collision was dragged for several miles to her death under the man's minivan, officials said Monday.

Authorities said they were still searching for the minivan's driver.

Sandra Hall was in a Cadillac that was struck by the minivan Sunday night, Broward County sheriff's officials said.

The minivan was driven away with the Cadillac in pursuit, and when both vehicles were stopped in traffic Hall got out and stood in front of the minivan, authorities said.

The minivan struck Hall, who became lodged underneath the moving vehicle, officials said.

Hall, 44, of Fort Lauderdale, was dragged for several miles before she fell from the undercarriage, authorities said. She was pronounced dead at the scene.
