A court heard that police officers had to use a Taser to subdue a man who had murdered his wife and children just hours after she was seen with another man.
Peter Nash, 47, is representing himself in court and denies murdering Jillu Nash, 43, and their autistic daughter Louise.
He is accused of murdering the couple in September last year at their home in Heath Estate, Great Waldingfield, Sudbury, Suffolk.
