OMAHA, Neb. — A Nebraska man charged in the deaths of his two young children waived extradition from California on Wednesday.

Adam Price, 35, appeared at a court hearing in San Mateo County, California, WOWT-TV reported.

He was arrested in Pacifica, California, on Sunday, hours after the bodies of his children — 5-year-old Emily and 3-year-old Theodore — were found at his home in Bellevue, an Omaha suburb.

Authorities haven’t said how or when the children died.

Price has been charged with two counts of felony child abuse resulting in death.

It was not immediately clear when Price would be returned to Nebraska or if he had an attorney to speak on his behalf.

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.
