Tony Farmer was Storme Turnay's partner at the time of her baby Soul's death.
One of the two people who could be responsible for killing baby Soul Turany has a history of troubled relationships and was served with a protection order, it can now be revealed.
The 16-week-old boy suffered catastrophic head injuries some time on the morning of 30 August 2014 and died in Christchurch Hospital the following day.
The assault broke Soul's skull in two places and caused bleeding to a vast tract of his brain and one eye.
Police say either the boy's mother Storme Turany or her then-partner Tony Farmer must have inflicted the injuries at the rural home they shared near Darfield.
