NEW ULM, Minn. (AP) - A Minnesota judge has issued an arrest warrant for the mother of a 13-year-old boy resisting chemotherapy after the pair missed a court hearing on his welfare.

Brown County District Judge John Rodenberg also is ordering that Daniel Hauser be placed in protective custody so he can get proper medical treatment for Hodgkins lymphoma.

Daniel and his parents, Colleen and Anthony Hauser, were due in court Tuesday to tell the judge results of a chest X-ray. But only Anthony Hauser appeared in court.

He told Rodenberg that he last saw Colleen Hauser on Monday evening, and she told him she was leaving. He said that was all he knew.

The family's doctor, James Joyce, testified that Daniel's tumor has grown and he needs immediate assessment by a pediatric cancer doctor.
