Taiwan Couple Are Suspected of Negligent Homicide in Building FireCHIAYI, Taiwan — Taiwanese prosecutors said that a couple were suspected of setting a fire and negligent homicide after 46 people were killed and dozens of others injured last week in the island’s deadliest building blaze in more than two decades. The prosecutors accused the 51-year-old woman, who was identified only by her surname, Huang, of failing to extinguish an incense coil when she left the 13-story mixed-used building in the southern port city of Kaohsiung early Thursday. The 52-year-old man, surnamed Kuo, was accused of failing to remind Ms. Huang to put out the incense. The authorities zeroed in on the couple, who are partners, on Friday. Ms. Huang was detained after being interrogated, while Mr. Kuo was freed on about $2,000 bail, prosecutors in Kaohsiung said.
