PHOENIX -- A possible road-rage incident led to the running of a red light and collision at a Phoenix intersection that killed a 48-year-old woman Sunday night.

Dustin Sommerfield, 27, is suspected of driving a Lincoln SUV through a red light at the Interstate 17 underpass at Thunderbird Road about 9:30 p.m. , colliding with a Dodge Neon driven by Constance Swenson, who was taken to a hospital where she died, Phoenix police Sgt. Vince Lewis said.

"I lost my sister and my best friend," says Swenson's sister, Salli Swenson. "I'll never get to laugh or be with her again."

Police said there was another occupant in the vehicle with Swenson. That person was not injured.

Sommerfield and Christina Moses, 34,  were involved in an aggravated assault incident in which Sommerfield is suspected of pointing a handgun at another driver while Moses drove the SUV.

Police tried to stop the SUV, but it fled, Lewis said.

Sommerfield and Moses are believed to have switched places at some point.

Police said Sommerfield drove the SUV from 19th Avenue west on Thunderbird Road without its headlights on before it collided with the car at the I-17 underpass.

Sommerfield was found a short time later and taken into custody, Lewis said.

Both suspects in the SUV showed signs of impairment, Lewis said.

Sommerfield was booked into the Maricopa County Jail on one count of manslaughter and Moses was booked for felony flight and DUI charges, Lewis said.

The crash closed the intersection until about 4 a.m. Monday.
