I've extracted these descriptions of the death of prisoners from torture by Americans, from an ACLU report. These are extracted from only a few of the of autopsies, released through the Freedom of Information Act. They were all ruled as homicides. Nobody has been charged in any of them.
These are the homicides from one of several pages of reports released. It's important to realize that information provided to the ACLU and other agencies on this is far from complete:
12/03/2002: Multiple blunt force injuries. Abrasion in upper right forehead. Abrasion on right lower forehead above eyebrow. Multiple contusions on right cheek and lower nose, left upper forehead, back of head. Abrasions on chest, lower costal margin. Contusions on arm, elbow, forearm, wrist, upper inner arm, groin, inner thigh, right back of knee and calf, left calf, left lower leg. Cause of death was pulmonary embolism due to blunt force injuries.
12/10/2002: Detainee was found unresponsive restrained in his cell. Death was due to blunt force injuries to lower extremities complicating coronary artery disease.Contusions and abrasions on forehead, nose, head, behind ear, neck, abdomen, buttock, elbow, thigh, knee, foot, toe, hemorrhage on rib area and leg. Detainee died of blunt force injuries to lower extremities, complicating underlying coronary artery disease. The blunt force injuries to the legs resulted in extensive muscle damage, muscle necrosis and rhabomyolysis. Electrolyte disturbances primarily hyperkalemia (elevated blood potassium level) and metabolic acidosis can occur within hours of muscle damage. Massive sodium and water shifts occur, resulting in hypovolemic shock and casodilatation and later, acute renal failure. The decedent's underlying coronary artery disease would compromise his ability to tolerate the electrolyte and fluid abnormalities, and his underlying malnutrition and likely dehydration would further exacerbate the effects of the muscle damage. The manner of death is homicide
06/06/2003: Died as a result of asphyxia (lack of oxygen to the brain) due to strangulation as evidenced by the recently fractured hyoid bone in the neck and soft tissue hemorrhage extending downward to the level of the right thyroid cartilage. Autopsy reveleaved bone fracture, rib fractures, contusions in mid abdomen, back and buttocks extending to the left flank, abrasions, lateral buttocks. Contusions, back of legs and knees; abrasions on knees, left fingers and encircling to left wrist. Lacerations and superficial cuts, right 4th and 5th fingers. Also, blunt force injuries, predominately recent contusions (bruises) on the torso and lower extremities. Abrasions on left wrist are consistent with use of restraints. No evidence of defense injuries or natural disease. Manner of death is homicide. DOD 003329 refers to this case as "strangulation, found outside isolation unit."
11/06/2003: Death caused by the multiple blunt force injuries of the lower torso and legs complicated by rhabdommyolisis (release of toxic byproducts into the system due to destruction of muscle). Manner of death is homicide. Decedent was not under the pharmacologic effect of drugs or alcohol at the time of death.
06/13/2003: Cause of death: Closed head injury with a cortical brain contusion and subdural hematoma. Manner of Death: Homicide. Iraqi male civilian detainee died in US custody 12 hours after a reported escape attempt. Physical force was required to subdue the detainee, and during the restraining process, his forehead hit the ground. Closed head injury: subarachnoid hemorrhage over brain, cortical brain contusion, right subdural hematoma. Additional injuries: fractured rib, multiple contusions and abrasions to head, torso and extremities. Abrasions on wrists and ankles consistent with restraint. Hemorrhage of right muscle of neck. No evidence of natural disease. DOD 003329 refers to this case as "1 closed head injury - died 12 hours after escape attempt."
08/08/2003: Iraqi National male was captured by Navy Seal Team #7 and resisted aprehension. External injuries including multiple contusions are consistent with injuries sustained during apprehension. Fractures of the ribs and a contusion of the left lung imply significant blunt force injuries of the thorax and likely resulted in impaired respiration. Ligature marks of the wrists and ankles. Remote gunshot would of torso. No significant natural diseases identified. According to investigating agents, during interrogation of the detainee, a hood made of synthetic material was placed over the head and neck of the detainee. He died while detained at Abu Ghraib prison in Iraq. Cause of death: Blunt force injuries complicated by compromised respiration. Manner of Death: Homicide. DOD 003329 refers to this case as "1 blunt force trauma and choking; died during interrogation." DOD 003325 refers to this case with the notation "Q[uestioned] by OGA [Other Governmental Agency - non-military, often refers to the CIA] and NSWT [Navy Seals] died during interrogation."
11/26/2003: Male detainee died while in U.S. custody. The details surrounding the circumstances at the time of death are classified. Cause of death: Asphyxia due to smothering and chest compression. Manner of Death: Homicide. Significant findings of the autopsy included rib fractures and numerous bruises, some of which were patterned due to impacts with a blunt object. DOD 003329 refers to this case as "1 blunt force trauma and choking; died during interrogation." DOD 003325 refers to this case with note "Q[uestioned] by MI [Military Intelligence], died during interrogation."
01/09/2004: 47 year old white male detainee died while in US custody. Cause of death: Blunt Force Injuries and Asphyxia; Manner of Death: Homicide. Autopsy revealed deep bruising of the chest wall, numerous displaced rib fractures, bruising on the lungs, hemorrhage into the mesentery of the small and large intestine. Examination of the neck structures revealed hemorrhage into the strap muscles and fractures of the thyroid cartilage and hyoid bone. History of asphyxia, secondary to occlusion of the oral airway. Pleural and pulmonary adhesions. Hypertensive cardiovascular disease. According to report provided by the US army CID, the detainee was shackled to the top of a doorframe with a gag in his mouth at the time he lost consciousness and became pulseless. The severe blunt force injuries, the hanging position, and the obstruction of the oral cavity with a gag contributed to this individual's death. DOD 00329 refers to this case as "gagged in standing restraint" DOD 003329 refers to this case as "1 blunt force trama and choking; gagged in standing restraint." DOD 003324 refers to this case with a note indicating "Q[uestioned] by OGA [Other Governmental Agency - non-military, often refers to CIA], gagged in standing restraint."
04/05/2004: This approximately 27 year old male civilian, presumed Iraqi national, died in US custody approximately 72 hours after being apprehended. By report, physical force was required during his initial apprehension during a raid. During his confinement, he was hooded, sleep deprived, and subjected to hot and cold environmental conditions, including the use of cold water on his body and hood. Flexcuffs used around each wrist. Abrasions and contusions around wrists. Minor abrasions and contusions of extremities. Laceration above right eyebrow, 1cm. Contusion of right side of neck. Minor abrasions of left side of forehead. Subgaleal hemmorrhage of bilateral frontal regions of scalp. Intramuscular hemorrhage of anterior aspect of right shoulder. No internal evidence of trauma. No significant evidence of natural disease. Drugs and abrasions consistent with defribilation efforts. Rib fractures consistent with CPR efforts. Concludes that cause of death cannot be determined. There is evidence of multiple minor injuries, including "blackeyes", abrasions and contusions of the face, torso and extremities, side of the next and subgaleal hemorrage of the scalp. The decedent was also subjected to cold and wet conditions and hypothermia may have contributed to his death. DOD 003323 refers to this case with the notation "Q[uestioned] by NSWT [Navy Seals], struggled/interrogated/died sleeping." Preliminary autopsy report of this individual is at DOD 003260 -003261. Death certificate is at DOD 003300.
