The offender Chamma - background, psychiatric and psychological history
- The offender Chamma is a 30 year old man, who was 28 years old at the time of the murder. The offender Chamma's background and psychological history was put before the Court by way of a report prepared by Dr Paul Pusey, Clinical and Forensic Psychologist, dated 22 July 2023.
- The offender Chamma has a nine year history of criminal offending prior to the current charge, including driving charges, drugs charges and firearms charges, some of which resulted in full-time custody. He has a limited history of violent offending. He was still subject to an Intensive Correction Order for an offence of stalk and intimidate when he committed the present offence.
- The offender Chamma is the second of four children. His parents' marriage ended when he was 16 to 17 years old. He said he had a good upbringing, at the same time as stating his father was a little violent to them and the Department of Community Services (DoCS) was called because of this. He denied being exposed to antisocial behaviour or drug use. His father was a strict Muslim so there was no drugs or alcohol around.
- The offender Chamma left school at Year 10, leaving school to support his ex-wife and their child when he was 15 to 16 years old. Following school, he commenced a mechanic apprenticeship which he left after two years. His last period of sustained employment was a long time prior to his most recent arrest. He found it difficult to get a job without a driver's licence.
- At the time of his offence, he was associating with people he had met in jail. He said he initially did the right thing, hanging out with his foster brother and working, but then "I met some boys from jail I know, and it all went downhill, because I started using and selling drugs".
- After the offence and prior to his arrest almost a year later, he told Dr Pusey that he stopped those associations and started hanging out with his new partner. He stopped using drugs and started hanging out with his family and seeing his children. This continued until his arrest.
- He told Dr Pusey he has been with his current partner for three and a half to four years, and for half of that time he has been in jail. He said that she keeps him out of trouble. He also has a good relationship with the mother of his children. She is a correctional officer, and he still considers her to be one of his best friends. The offender Chamma has three children aged 13, 10 and 8, who live with their mother.
- At the time of his assessment, the offender Chamma said he was free of illicit substances and had been on the "bupadiol program" in custody for eight months, his first such engagement with treatment for drug dependence. He claims to have been "clean since about one month after the murder".
- He stated to Dr Pusey that two or three months prior to the murder he had started to use ice again, as well as some cocaine. Dr Pusey opined that at the time of the offending the offender Chamma would have met the diagnosis of Substance Use Disorder.
- As to his mental health, he had been diagnosed with depression and anxiety in custody and has been prescribed medication. He attributed the cause of these conditions as being "the trial, my conviction of murder despite not doing it, what happened and not knowing the length of my sentence".
