Case profile – Newton Silva

Posted on 03/08/2022

Newton Silva was found dead on the side of a dirt road at Dowlingville, about 10kms from Ardrossan on the Yorke Peninsula on 3 August 1988.

The 36-year old had been shot twice in the head and once in the heart. The subsequent investigation found that he had been murdered on 15 July 1988.

Mr Silva lived in the northern suburbs of Adelaide and mixed with people who were involved in the sale and distribution of illegal drugs.

In early July 1988, in the weeks before his death, an associate believed Mr Silva had stolen $7000 in drug money from him, so he and a friend had beaten Mr Silva with a pool cue and a baseball bat causing severe injuries.

Six people were charged in relation to Mr Silva’s murder and were accused of being involved in abducting him from his Salisbury Plains flat.

Two were convicted but released on appeal. No retrial was held as a crucial witness had died in the meantime.

A reward of up to $200,000 remains on offer to anyone who provides information leading to a conviction in the case.
