Mysterious Obelisk In Utah Disappears; World AIDS Day

A week after its discovery, a mysterious 9-foot steel obelisk in the Utah wilderness has disappeared. No one knows who removed the object. Zak Podmore of The Salt Lake Tribune reports. Also, nearly 40 years after HIV/AIDS was first detected, more than 30 million have died. One of the co-founders of activist group ACT UP reflects on what progress has been made since the 1980s.
