Washington: The teenage Indian-American university student was chokehold by her assailant until she passed out after she refused to talk to him or acknowledge his catcalls, then she was dragged to the back seat of her car and sexually assaulted, prosecutors said. The gruesome details emerged during a bail hearing of the 26-year-old assailant Donald Thurman, charged with first-degree murder and criminal sexual assault of Ruth George, 19. The prosecutors told the court on Tuesday that Thurman had confessed to the crime and it ordered he be held without bail.

George, originally hailing from Hyderabad, was a student at University of Illinois in Chicago and was found dead in family-owned car in a campus garage Saturday. The medical examiner has ruled her death a homicide by strangulation. Cook County prosecutor James Murphy said Thurman became angry after George did not respond to his catcalls when she was walking from the campus to the parking garage early Saturday. He then followed George to the garage.
