Chad Daybell, the husband of “doomsday” mom Lori Vallow, laughed and smiled during his first court appearance Wednesday since being charged with murdering his stepchildren and his ex-wife. Dressed in a white button-down shirt and a red tie, Daybell, 52, had a slight smile on his face when the virtual court appearance kicked off at 11 a.m. local time in Fremont County, Idaho. When Judge Faren Eddins asked if Daybell could hear him, he broke out into a toothy grin and appeared to laugh before leaning forward and answering, “Yes.” As Eddins then read out the eight charges against Daybell — which include raps of first-degree murder for the death of Vallow’s two kids, 17-year-old Tylee Ryan and 7-year-old Joshua “JJ” Vallow, and ex Tammy Daybell — the prolific doomsday writer maintained a slight smile on his otherwise emotionless mug. #ChadDaybell #LoriVallow #Doomsday The New York Post is your source for breaking news, news about New York, sports, business, entertainment, opinion, real estate, culture, fashion, and more.
