Rapes, killings hit Katrina refugees in New Orleans
"They killed a man here last night," Steve Banka, 28, told Reuters. "A young lady was being raped and stabbed. And the sounds of her screaming got to this man and so he ran out into the street to get help from troops, to try to flag down a passing truck of them, and he jumped up on the truck's windshield and they shot him dead."
