Craig McDermott, Ms Warzywoda's long term defacto partner, was on Wednesday jailed for 25 years for stabbing her to death in a Sunshine car park.

The sentencing judge said McDermott, the father of Ms Warzywoda's four children, showed no remorse. Here is his timeline of abuse.

• March 28, 2010 A drunk McDermott grabs Fiona by the throat, pushes her to the floor. After she escapes with their children, he splashes petrol around the house, goes after them and threatens to burn the house down. He pleads guilty to crimes over the incident and receives a suspended sentence.
• February 15, 2014 Couple separate at a family party. Realising his car keys had been hidden after he had too much to drink, McDermott smashes Fiona's car window and kicks the car's front panel. 
• February 17, 2014 McDermott consents to an interim family violence order made against him at Sunshine Magistrates' Court.
• February 24, 2014 He moves out of the couple's home. Fiona does not bar him from contacting children, and facilitate their visits.

• March 12, 2014 He fails to return the children to Fiona after a visit as promised, keeps them for another 12 days until ordered by a court to return them. During that time, he limits their contact with their mother, and only takes them to school for one day. He also makes a threat in front of the children to kill their mother with a pocket knife.
• March 24, 2014 Federal Circuit Court orders he return the children that day and allows him access to them in future.
• March 26, 2014 Fiona successfully applies for stricter conditions on the intervention order, which McDermott agrees to, including orders not to contact her or the children or go within 200 metres of their school, home and workplace. It also orders him not to approach Fiona or the children, not to try to find them, and to remain 5 metres from them.
• April 2, 2014 Fiona applies to suspend children's contact with McDermott to align the updated intervention order with the child custody order.
• April 15, 2014 Federal Circuit Court orders McDermott cease contact with his children pending a psychiatric assessment report. It rules that he would then be allowed supervised visits at specific times. The court also allows Fiona to move to Bendigo with their children. Security guard sees McDermott outside the court and overhears him saying "I'm going to slice her."
• April 16, 2014 McDermott arrives at Sunshine Magistrates Court, walks past Fiona saying, "You're fucked". She reports this to court staff and her solicitor. The court makes the interim intervention order against McDermott final. Hours later, he stabs Fiona to death in a 30-second attack outside a Sunshine shopping centre, killing her.
