FORT LAUDERDALE, Fla. (AP) _ An Idaho couple were sentenced to prison for selling ozone-generating machines they claimed could cure AIDS and cancer.

Kenneth Thiefault, 58, and his wife, Mardel Barber, 52, of Kooskia, Idaho, sold the machines for about $4,800 each to customers across the United States, prosecutors said.

``These machines can actually harm people,'' prosecutor Rolando Garcia said Wednesday. A biology professor who testified at the couple's fraud trial said inhaling ozone in high concentrations can cause cancer, he said.

Thiefault was sentenced Monday to more than six years in prison and fined $100,000. His wife got nearly three years and a $60,000 fine.

The couple had recommended that the ozone be administered rectally, vaginally, in the ear or through the skin by using a body bag, according to prosecutors.
