Indonesian prosecutors say three women arrested last month, including an Iowa nurse, may now face espionage charges. 56-year-old Joy Lee Sadler of Waterloo has been in custody in Indonesia since September 11th on charges of immigration violations. She and the others were accused of having contact with rebels to the Indonesian government. Sadler says she’s innocent of the charges. She’d gone to that nation to help treat the sick and injured in refugee camps. She could face up to 20 years in prison if convicted.
