Season 1

Carl Anthony Williams, a convicted murderer and drug trafficker from Victoria, rose to prominence as the central figure in Melbourne's gangland killings. He was sentenced to life imprisonment with a non-parole period of 35 years for ordering the murders of three people and conspiring to murder a fourth (which was unsuccessful). On 19 April 2010, while imprisoned at Barwon Prison, Williams was beaten to death with the stem of an exercise bike by fellow inmate Matthew Charles Johnson.
