No new leads on missing Minn. mother, son

Brown County authorities said they had no new leads on the whereabouts of Colleen and Daniel Hauser. Anthony Hauser, her husband and the boy's father, didn't respond to phone messages.

Colleen Hauser fled with their son Daniel on Monday after a doctor told them a cancerous tumor in Daniel's chest was growing. Doctors have said he needs chemotherapy for his Hodgkin's lymphoma, but the Hausers prefer alternative remedies.

Colleen and Daniel were last seen Tuesday in southern California, possibly on their way to Mexico, authorities said.

On Thursday, Anthony Hauser appeared before reporters asking his wife to "do what's best for Danny."

The Hausers favor natural healing methods inspired by American Indian traditions, but several doctors have testified Daniel's cancer will likely kill him without chemotherapy.

The American Cancer Society estimates there are 35 to 50 clinics in Mexican border towns that attract cancer patients looking for alternatives to traditional U.S. treatment methods. Many of these clinics have offices in the San Diego area that serve as contact points for U.S. patients, who are then referred to clinics in Mexico.
