Diane Corado has been missing since she and a friend were kidnapped from her Levittown home last month. The friend was later released, while police found Corado's blood-stained car and ex-boyfriend Kenneth Patterson later that day in New Jersey.
The 48-year-old Patterson is due in court Wednesday afternoon in Bucks County after waiving extradition. He will be arraigned on kidnapping and related charges.
But Bucks County District Attorney David Heckler plans to charge Patterson with murder and seek the death penalty.
Heckler says it's a strong circumstantial case, even if the 57-year-old Corado's body is never found.
