The man who killed a Melbourne heart surgeon after an argument over smoking will spend at least 10 years in jail after becoming the first person sentenced under Victoria’s one-punch laws. Joseph Esmaili was sentenced to 10 years and six months’ jail, and the one-punch legislation means he will not be eligible for parole until serving 10 years. The 24-year-old punched Patrick Pritzwald-Stegmann in the head at Box Hill Hospital, in Melbourne’s east, in May 2017. The blow knocked the surgeon unconscious and caused him to fall backwards and hit his head on the tiled floor. He died in hospital a month after the attack.
