Army Spc Charles Graner Jr, the reputed ringleader of a band of rogue guards at Abu Ghraib, was convicted of abusing Iraqi detainees in a case that sparked international outrage when photographs were released showing reservists gleefully torturing and sexually humiliating prisoners.
Graner, the first soldier to be tried on charges arising from the scandal, was convicted on Friday of all five charges and faces up to 17-and-a-half years behind bars.
The jury took less than five hours to reach the verdict.
The verdict came after a five-day trial in which prosecutors depicted Graner as a sadistic soldier who took great pleasure in seeing detainees suffer.
He was accused of stacking naked prisoners in a human pyramid and later ordering them to masturbate, while other soldiers took photographs.
