Bradley Robert Edwards was living in his Kewdale home when police carried out an early morning raid on his house, arresting him and taking him into custody in December, 2016. To those around him, the 50-year-old appeared to live an ordinary life. He had worked for Telstra as a technician all his adult working life, and until shortly before his arrest, lived with his wife and step-daughter. The former Belmont Little Athletics president was heavily involved in the Belmont and Kewdale Little Athletics clubs. He would have been 26 and 27 years old when the alleged murders occurred.

He has pleaded not guilty to all the charges against him. During court appearances, he appears neatly presented and sits quietly. The Judge: His Honour Justice Stephen Hall Supreme Court Justice Stephen Hall has been selected to preside over Mr Edwards' trial. Supreme Court of Western Australia Judge Stephen Hall has been selected to determine Mr Edwards' innocence or guilt.

"Time has not healed our loss, even after 20 years. Words are inadequate to describe our personal loss and heartbreak," it read. "It's hard not to wonder what Sarah's life, and ours, could have been had she not been taken from us. "She was so full of life and had a great love of family."
