Lori Vallow Daybell has been found guilty of murder in the deaths of her two children and a romantic rival after a three year trial. Prosecutors argued she was a power-hungry manipulator who killed her children for money, while the defense team said she was innocent. Her husband, Chad Daybell, is still facing trial for murder and other related offenses. The case will be featured in a special episode of "48 Hours" titled "Lori Vallow Daybell: Guilty" that will air on CBS and stream on Paramount+ on Saturday, May 13.
