Vilseck, Germany (CNN)  -- The wives of three Army sergeants in prison for premeditated murder say their husbands are war heroes who should not be in prison. "I can sympathize with them that they felt like there was nothing else they could do," said Jamie Leahy, wife of Sgt. Michael Leahy, a 28-year-old medic. She said her husband and the other two sergeants were heroes for protecting other soldiers. Leahy, 1st Sgt. John Hatley and Sgt. 1st Class Joseph Mayo killed four Iraqi men whom they had taken into custody at a canal in Baghdad, Iraq. During the investigation of the killings, Leahy told Army investigators that the same men they had captured would be shooting at them again if they had released them.

Earlier this year, Leahy, Hatley and Mayo were convicted of premeditated murder and conspiracy to commit premeditated murder in the killings of the four
Iraq detainees in March 2007.
