A Vancouver man suspected of starting a fire that killed five of his children and himself had been arrested last month after a fight with his wife.
Tuan Dao was arrested March 30 over allegations he threw an iron at his wife. It missed her but the cord hit a child.
The next day a Clark County judge ordered the 37-year-old not to come within 500 feet of Lori Dao and to have a third party with him when he wanted to see the children.
Police say Tuan Dao is the only suspect in Sunday's fire that killed five of his children, ages 12 and under. A 13-year-old daughter and the mother had moved to another address.
The couple filed for bankruptcy last fall.
