The monument commemorates George Duncan, a Law lecturer at the University of Adelaide, who was savagely beaten and drowned after being thrown into the River Torrens in 1972. The monument was erected near the site of the murder on the 30th anniversary of his death.  

The plaque on the monument is in the shape of a triangle, and in NAZI Germany known homosexuals were send to the concentration camps and were signified by having to wear a pink triangle.  Other groups (Jews, Gypsies, and others) in the concentration camps had to wear a similar badge but in a different colour. In the early days of the Australian homosexual liberation movement, around the early 1970s, the pink triangle was reclaimed as sign of liberation. 

Dr Duncan's murder never resulted in a conviction and it was very controversial due the fact that Dr Duncan was a homosexual and it was believed that members of the police force were implicated in the crime.  

On 30 September 1988, two ex-members of the vice squad were acquitted of Duncan's manslaughter. A police task force interviewed eighty-one people and reported to parliament in April 1990 that there was 'insufficient evidence to charge any other person'.

His murder was significant because public outrage generated by the murder became the trigger for homosexual law reform that led to South Australia becoming the first Australian State to decriminalise homosexuality.
