The Vancouver man suspected of starting the fire that killed five children and himself had been arrested last month after a fight with his wife.
The 37-year-old Tuan Dao was arrested March 30 and accused of throwing an iron at his wife. It missed but the cord hit a child. The next day a Clark County judge ordered him 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 the Sunday fire that killed five of his children, ages 12 and under. A 13-year-old daughter and the mother had moved to another address.
