THE WOMAN stabbed to death during a violent rampage in New Zealand was the suspect's former wife, police have revealed. Heidi Welman Scott, 42, was stabbed to death at her Mahoney Drive, Albany home just before 9am (7am AEDT) today, while her 22-year-old daughter, Taryn Welman, and her boyfriend, also 22, sustained serious injuries in the attack. Heidi Welamn, 42, was stabbed to death at her Albany, New Zealand home on November 27, 2014. Her estranged husband, Brent Scott, was arrested in relation to the stabbing. Detective Inspector Bruce Scott said while the couple remained in a critical condition, they have both had surgery, leaving police feeling optimistic about their recovery, New Zealand Herald reports. After a large-scale, frantic manhunt, police arrested 45-year-old Brent Scott - believed to be the father of Ms Welman and a 14-year-old boy, who was at Rangitoto College when the attack occurred - at Auckland International Airport after he tried to flee the country. Inspector Scott said the suspect was attempting to fly back to his former home in South Africa, but was "detained by police until our detectives arrived." It is understood Scott was driven to the airport by a female friend after first "fleeing the address on foot," Inspector Scott said. The woman is assisting police with their inquiries. Police also revealed that Scott was due to attend court today for allegedly breaching a previous protection order regarding his and Ms Scott's 14-year-old son. According to news site stuff.co.nz, Scott was arrested and charged with family violence offences during a holiday to South Africa in 2013. Inspector Scott highlighted that the attack took place during White Ribbon week, a program created to end domestic violence. "To say that this was a tragedy was an understatement," he said. This week is White Ribbon week and the police and community have been gathering together to oppose family violence. Inspector Scott said an autopsy would be "conducted either today or tomorrow." Neighbours told New Zealand Herald this morning that they heard screaming just before 9am, but because "it didn't last too long, they didn't think it was anything bad." Several schools - including Rangitoto College - were put into lockdown after police revealed Scott could still be in the area. Kristin School and Albany Primary School were also put in lockdown as police searched for Scott.
