WILKES-BARRE, Pa.—A Pennsylvania tow truck driver has been convicted of homicide by vehicle and other charges in the death of a woman he hit with her own car.

On Friday, a jury found 56-year-old Robert Wickham guilty of homicide by vehicle while DUI and two counts of DUI. He's scheduled to be sentenced Nov. 7.

Wickham acknowledged drinking 24-ounce beers before arriving to help 55-year-old Denise Polinchak on a snowy March 2011 evening in Plains Township, Luzerne County. But he had told the jury Thursday that the car's faulty brakes and Polinchak's failure to heed his warning to move away are the reasons for her death.

He says he threw two more unopened beers over a snow bank after backing into Polinchak only because he was scared.
