One woman killed, after she is ejected from a pickup, that swerved to avoid a slow-moving car, and is then struck by another pickup, that fled the scene, on eastbound I-10 near Phoenix.

Eastbound Interstate 10 has been reopened after a deadly hit-and-run crash Monday night.

A pickup truck, driven by Randall Wayne Owens, 54, was speeding down the Ray Road ramp onto eastbound I-10 when the driver swerved to avoid a slow moving car, an Arizona Department of Public Safety spokesman said.

That maneuver somehow caused a woman, later identified as Celia Ester Owens, 44, riding in the truck who was not wearing a seat belt to be ejected, and she was struck by another pickup, the spokesman said.

The driver of that second truck did not stop, and officers are investigating the incident as a homicide.

The 8:20 p.m. crash closed eastbound I-10 for several hours.

No other information was immediately available.
