Insights from Week 2 of Lori Vallow Daybell murder trial.

The murder trial of Lori Vallow Daybell, accused of killing her two children and her husband's ex-wife, has entered its third week of testimony. The case is largely circumstantial, with no eyewitness accounts of the deaths. Among the most interesting evidence presented was a recording of a jail phone call between Daybell and her son, in which she denied murdering her children and claimed they were "fine." Prosecutors also highlighted the role of Daybell's brother, who died from natural causes, and her unusual religious beliefs. The trial is expected to last for eight to 10 weeks.
