Not everything “Dateline NBC” does is true crime; the show has done hours on the Capitol riot, COVID-19 vaccine development and the George Floyd case in the past year.

Vallow is currently awaiting trial for multiple charges, including two felony counts of desertion and nonsupport of children, according to a criminal complaint filed with an Idaho court.
