A call from a payphone near the scene of an unsolved double murder could be key to cracking a decades-old cold case as police offer a $1 million reward for information.
Susan Kay, 32, and Joanne Teterin, 37, were bludgeoned to death in a suburban Newcastle home on May 17, 2000.
A coroner determined in 2003 they were murdered by an unknown person but no arrests or charges have ever been laid.
