Julian Ingram was convicted of grabbing a family member by the throat after she made a comment about his children four years before he allegedly murdered three people and went on the run.
Ingram, also known as Julian Pierpoint, is suspected of shooting dead his pregnant former partner Sophie Quinn, her new boyfriend and her aunt last month in Lake Cargelligo, about 450km west of Sydney. The 37-year-old was later seen leaving the town in a white single-cab Ford Ranger.
