Mr Pumpa was born in Canberra ... . His parents separated in 2004 when he was aged approximately 9 years and he subsequently lived with his mother. His father reported that the separation was not amicable and resulted in conflict over access for approximately nine months. After this time, Mr Pumpa spent weekends with his father as well as some evenings during the week.
After their divorce both of his parents repartnered. Mr Pumpa has [three half siblings].
He described his childhood as unremarkable, stating that while his parents were together, his father tended to "be in charge". Following their separation, however, he advised that "everything went downhill" because his mother suffered from mental health issues and provided minimal and inconsistent discipline. According to [an earlier presentence report], Mr Pumpa's mother advised that he was "distraught" during the separation, and he advised that it was "difficult" for him to see his parents with new partners.
Despite his mother's difficulties, Mr Pumpa reported that he felt close to his mother and felt sorry for her, as she had lost her job after returning from maternity leave and remains unemployed. He stated that she drank heavily, was abusive and violent, and that he felt she was a "negative influence" on his life, frequently harassing him about getting a job and about money, and being abusive and aggressive towards his girlfriend. He stated that he tried to avoid her when she was drinking but they frequently fought particularly when he felt the need to defend his girlfriend, ... He also described his mother as lacking "forward planning" skills and "being in denial" about the reality of the separation.
Mr Pumpa also stated however, that he was more like his mother in terms of personality, while his brother was more like his father. Mr Pumpa describes his father as "too strict" and "controlling" and reported that they hadn't talked since early in the year when his father had withdrawn his financial support for his legal matters. Where he had previously stated that he now felt that he was becoming more like his father who was more "responsible and mature", and that he was starting to "settle down", he now described himself as lacking motivation and focus, stating that he was drifting through each day with little sense of purpose.

Ms Rebecca Barnes, Mr Pumpa's aunt, has provided additional information about Mr Pumpa's developmental and family history in the form of a character reference.
In her statement, Ms Barnes describes Mr Pumpa's history of depression which she attributes in part to his parents' divorce in 2004. She states that the impact of growing up without a strong father figure, and a mother with mental illness has "had a profound effect on his ability to enter manhood successfully". This is consistent with Mr Pumpa's father's advice at the time of my previous report in November 2013, that there was little continuity in his influence over Mr Pumpa following the divorce.
Ms Barnes also states that Mr Pumpa blames himself for his parents' divorce, and his mother's illness, which has caused him to feel hopeless and to mourn the loss of a healthy mother and normal childhood. This is partially consistent with Mr Pumpa's own statements that he felt "close to" and "sorry" for his mother, and remained in contact with her out of loyalty.
