2011: Killed Behind Bars: Matthew Johnson Convicted of Murdering Gangland Assassin Carl Williams
Carl Williams had already been convicted of multiple murders during Melbourne’s gangland war when he was bashed to death with the stem of an exercise bike in a high-security unit at Victoria’s Barwon Prison in 2010, an inmate supposedly protected by round-the-clock surveillance.
Matthew Charles Johnson, a fellow prisoner sharing the unit, was charged with the killing. On this day in 2011 a jury found him guilty of murdering the man once considered one of the country’s most feared underworld figures, in an attack that exposed how little safety the prison’s most secure wing actually offered its most notorious inmate.
