A Mt. Lebanon woman died this afternoon, a day after she was struck by an SUV while pushing her two toddlers in a jogging stroller.

Lisa Styles, 36, died about 1:30 p.m. at UPMC Mercy, where she had been treated for a severe head injury.

Ms. Styles and her 3-year-old son and 1-year-old daughter were struck when the SUV turned right from Beadling Road onto Washington Road at 12:14 p.m. Monday. Police said the car failed to stop at the stop sign and struck Ms. Styles and the stroller as she crossed Beadling Road.

The stroller was flipped onto its side by the collision, but the two children were conscious and alert when witnesses removed them, police said. They were taken to Children's Hospital of Pittsburgh of UPMC with no obvious injuries.

Police named Benjamin T. Cope, 20, of Mt. Lebanon, as the driver of the SUV. He will be charged with driving while impaired and driving while under the influence of a controlled substance. Police believe he was high on marijuana when he struck Ms. Styles.

Records indicate that Mr. Cope has paid $755 in fines to Mt. Lebanon, South Fayette and Pittsburgh since February 2006 for traffic violations that include speeding, disregarding a traffic control device and driving without a license.
