From News Talk 770 Website :
The man accused of killing former News Talk 770 sports director Billy Powers and his wife Donna Lee in July 2013 has pleaded not guilty to two counts of second-degree murder.
At a hearing today to determine Derek Puffer’s mental state at the time of the crime, the courtroom heard the gruesome details of the final night of Billy & Donna Powers life, when the couple were stabbed a combined 25 times. Puffer was the adopted son of Donna Lee. The murders occured at the couple’s Braeside home.
In an agreed to statement of facts, court heard of the communication between Puffer and arresting officers on the night of the murders. Puffer said “I’ve been hearing voices, did you find the knife? They’re in the bedroom, they put a chip in my brain”.
It’s expected the defence will try and prove Puffer was not legally sane at the time of the murders, as his medical history includes an unmediated battle against schizophrenia dating back to 1995.
