Stephen Boyd, 51, had prior convictions for breaching an apprehended violence order and for violent offences committed against his partner and son, an extradition hearing was told on Thursday.

Police found Ms Kontozis, 51, dead in her Beachcomber Avenue home after being alerted by neighbours who heard fighting and screaming about 3.30pm on Sunday. A much-loved resident of the tight-knit southern Sydney village, Ms Kontozis worked at the local day care centre.

She had allegedly been beaten to death. A 17-year-old youth injured in the attack was taken to hospital.

Mr Boyd was arrested at the ACT town of Braidwood the next day after an extensive manhunt. He broke his jaw and suffered a neck injury when his car hit an embankment following a police pursuit. He was treated at Queanbeyan and Canberra hospitals under police guard.

The accused killer wore a neck brace and green tracksuit when he faced the ACT Magistrates Court on Thursday afternoon. He rubbed his eyes and sighed deeply as he waited for his case to come before Magistrate Karen Fryar.

​NSW police sought his extradition on a warrant for charges including Ms Kontozis's murder, assault occasioning grievous bodily harm and breaching an apprehended domestic violence order.

Questioned by prosecutor Shane Drumgold, Detective Sergeant Belinda Abdy, of Sutherland Local Area Command, told the court Mr Boyd had prior convictions for breaching the protection order and for violent offences committed against his partner and son.

Mr Drumgold said there were concerns Mr Boyd would fail to appear at court, given the difficulty police had in apprehending him, and could commit further offences if he was released from custody.

After Ms Fryar granted the extradition request, Mr Boyd was taken into the custody of NSW Police to face court in Queanbeyan on Friday.
