Price has been charged with two counts of felony child abuse resulting in death.
Price filled out paperwork to get an attorney while in the California county jail, which would have prompted an extradition hearing at another time. Instead, he changed his mind and decided not to fight extradition.
It was not immediately clear when Price would be returned to Nebraska.
The children were with Price for a court-ordered visitation. Their mother, Mary Nielsen, who lives in Illinois, called police Saturday after she couldn’t reach the children. Police said they did not have sufficient reason to enter the home.
A friend’s of Nielsen’s went to the home Sunday at her request and found the children’s bodies.
