SEAGOVILLE - A woman was killed and her daughter and two grandchildren were hospitalized after a rollover accident in Seagoville Monday morning.
Investigators say freezing water from a sprinkler system in front of an Auto Zone store may have contributed to the crash.
The Dallas County sheriff's office said the accident happened about 5:20 a.m. on the icy service road of U.S. Highway 175 near Malloy Bridge Road.
The woman, identified as 44-year-old Pamela Godfrey, was ejected from the pickup truck and pronounced dead at the scene.
Also in the car at the time of the wreck were Godfrey's daughter, Ashley Duren, 23, and two grandchildren, two-year-old Willow and six-year-old Joshua. They were taken to Baylor University Medical Center for treatment of minor injuries.
According to the Texas Department of Transportation, maintenance workers notified businesses in the area about turning off their sprinklers during freezing weather.
The City of Seagoville recently approved a new ordinance relating to sprinkler systems. It says, in part: "Freeze and moisture sensors will be placed in each controller to prevent irrigation systems from activating during freezing weather (creating unsafe spillage and ice on roads and/or sidewalks)..."
Fines for violators range from $500 to $2,000 a day.
Seagoville City Manager Denny Wheat told News 8 the businesses in question were not in violation of the ordinance because changes don't have to be made until January 1, 2009.
Auto Zone officials were cooperating with the investigation.
