On 12 March 2007, Frank Newbery was beaten to death inside his convenience store, Franks Ham & Beef, in the inner-city suburb of Cooks Hill in the Australian city of Newcastle. The murder remains unsolved and the New South Wales Government offers a reward of $100,000 for any information leading to an arrest and conviction. Using only the above description and what you know about the world, "Frank Newberry's killer was not convicted of murder." is definitely correct, incorrect, or inconclusive?
