The Pittsburgh Tribune-Review ( http://bit.ly/TUKHYi) reports 51-year-old Duane Woodson will be sentenced Jan. 3 on those charges and an unrelated drug possession case.
Police say Woodson's crash killed the driver of the other vehicle, 45-year-old Christine Beilstein, of Plum, and left her 9-year-old son, Justin, with a severe head injury.
The boy's father, William Beilstein, of Deatsville, Ala., didn't attend Monday's guilty plea because he was with his son who was having related surgery at Children's Hospital of Pittsburgh of UPMC.
Woodson ran away after the May 12 crash, but was brought back to the scene by a witness.
