22-year-old John Okie has pleaded not guilty by reason of mental defect to the charges.
Okie’s ex-girlfriend, 19-year old Alexandra Mills was beaten to death in her family’s home in July of last year.
Six days later, Okie’s father, 59-year-old John Okie, was found dead in Newcastle. He had been stabbed to death.
The younger Okie has been held without bail since being arrested just hours after his father’s body was found.
