Michael and Cathryn Borden, both 50, were found shot to death shortly after 8 a.m. Sunday, after the couple's 9-year-old son ran to the home of neighbors, who called 911. An older daughter also escaped, police said.
But Kara Beth Borden, 14, was missing since that morning at the family's home in Warwick Township, about 60 miles west of Philadelphia, and may have been abducted at gunpoint by Ludwig.
"We think they're boyfriend and girlfriend," Seace said. "The young girl was out during the night, came home, and her parents confronted her. From what we understand, he came to the house."
