Police have not said how the children died. The charges do not specify how Price allegedly caused the children’s death, The Omaha World-Herald reported.
The children’s mother, Mary Nielsen, told reporters that she and Price are in the process of getting divorced and the children were at their father’s home for court-ordered visitation.
Nielsen, who had moved to Illinois with the children, called police more than once and went on social media to plead for information on her children’s whereabouts after not hearing from them since Thursday. Nielsen said her husband was under court order to provide her daily communication with the children during his visits.
