[AJC] A two-decade family feud came to a violent end when a man rubbed out the two home invaders that killed his wife and son, not knowing the assailants included his long-estranged daughter, authorities said Sunday.Though the investigation of Friday's shootings continues, authorities said it appears Josephine and Jeffrey Ruckinger planned to murder her family at their rural central Pennsylvania home -- but it remains unclear what exactly led to the deadly confrontation.
"They parked at the bottom of a long driveway, and walked up, heavily armed," said Cambria County District Attorney Kelly Callihan.
