Robert Wickham acknowledged drinking the 24-ounce beers before arriving to help 55-year-old Denise Polinchak on a snowy March 2011 evening in Plains Township, Luzerne County.
But Wickham told the jury Thursday 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.
Wickham faces vehicular homicide and DUI charges.
The jury began deliberating after Wickham's testimony. Deliberations are set to restart Friday.
