Middleton Jamar O'Neal Clark 15-6355 Page 3 ADDITIONAL PERSONNEL PRESENT AT AUTOPSY: • • Special Agent C. Michael Phill II, Minnesota Bureau of Criminal Apprehension Special Agent Kevin M. Cane, Federal Bureau of Investigation IDENTIFICATION: Positive identification is made by comparison of antemortem and postmortem fingerprints (Minnesota Bureau of Criminal Apprehension). EXTERNAL EXAMINATION: The body is that of a normally developed, adequately nourished appearing, 70 inch long, 168-pound male whose appearance is consistent with the reported age of 24 years. Lividity is posterior and dependent, and blanches with very firm pressure. Rigor mortis is beginning to develop in all of the extremities. The protected parts of the body are still slightly palpably warm. The scalp is covered with long, black hair tightly coiled into dreadlocks. The right iris is brown, and the pupil is round. There are no right-sided bulbar or palpebral conjunctival petechiae. Assessment of the left eye and periorbital tissues is limited by injury (further described below). The external auditory canals are free of blood. The ears are unremarkable. Abundant bloody fluid emanates from the nares. The nares are otherwise patent. The lips are atraumatic (except for medical intervention described below). The nose, right maxilla, and mandible are palpably stable. The teeth appear intact, are native, and are in good repair. A black mustache and goatee style beard are on the face. The neck is straight, and the trachea is midline. The chest is symmetric. Prominent, hypopigmented stretch striae are on both anterior axillary lines, extending onto the lateral pectoral regions and onto the anterior aspects of each arm. A pair of vertically oriented, 5.5 and 7 cm long co-linear scars is on the left side of the chest extending onto the left epigastrium. The abdomen is flat. A 3 cm long, hyperpigmented scar is on the far right side of the abdomen. The genitalia are those of a normal adult male. The testes are descended and free of masses. Pubic hair is present in a normal distribution. The back, buttocks, and anus are unremarkable. Jamar O'Neal Clark 15-6355 Page 4 The upper and lower extremities are symmetric and without clubbing or edema. The nails of the hands are trimmed very short and are focally dirty, but are otherwise unremarkable. Approximately thirteen round and linear hyperpigmented scars, ranging from less than 0.5 cm diameter to 3.5 cm long, are scattered across the lateral surface of the right arm, over the posterior right elbow, and on the posterolateral right forearm. A faint, 0.6 cm long, linear scar is on the dorsum of the right wrist. A 3 cm long faint, obliquely oriented scar is on the anterior right wrist. Multiple 0.2 to 0.7 cm maximum dimension oval and linear scars are scattered across the dorsum of the right hand, primarily over the metacarpal-phalangeal joints. Approximately eleven oval to linear scars, ranging from 0.2 cm maximum dimension to 4 cm long, are scattered across the lateral aspect of the left arm and over the left elbow. Five macular, hyperpigmented, oval scars ranging from 0.3 cm to 1.5 cm maximum dimension are scattered over the posterior and medial left wrist. Patchy, nondescript scars are scattered over and around both knees, more pronounced on the right. The nails of the toes are unremarkable. TATTOOS: • • A 14 cm maximum dimension monochromatic blue tattoo of an animal head-like figure with associated scroll work is on the anterior right forearm. A 17 cm maximum dimension monochromatic blue tattoo that appears to be an outline of the state of Minnesota is on the anterior left forearm. MEDICAL INTERVENTION: • • • • • • • • • • • Hospital bracelets (2), right wrist Intravascular catheter, anterolateral right forearm Intravascular catheter, right antecubital fossa Urinary bladder catheter with attached tubing and collection bag Hospital tag, right 2nd toe Intravascular catheter, dorsolateral left forearm Intra-arterial vascular catheter, left radial artery Triple-lumen intravascular catheter, left subclavian Gauze and medical tape covering the left eye and cheek Electrocardiographic lead, left shoulder Dried, curvilinear orange abrasion (2.5 cm long) over the distal sternum, suggestive of cardiopulmonary resuscitation Jamar O'Neal Clark 15-6355 Page 5 • • • Linear, dried brown abrasion (2.5 cm long) extending from the left corner of the mouth and in direct continuity with a faint, 8 cm long line along the left side of the jawline, suggestive of a strap for an endotracheal tube Linear, dried brown abrasion (1.5 cm long) extending from the right corner of the mouth, suggestive of a strap for an endotracheal tube Healing, focally dried black and scabbed abrasion (1.5 cm maximum dimension) on the lateral aspect (cutaneous and mucosal surfaces) of the right side of the lower lip, consistent with oral endotracheal intubation RADIOGRAPHS: Review of the decedent’s antemortem CT scan demonstrates a main projectile in the right side of the cranial vault in the region of the right occipital lobe; numerous minute metal fragments project in and around a fractured left orbit. EVIDENCE OF INJURY: GUNSHOT WOUND OF THE HEAD: Just lateral to the left eye, 5 inches below the top of the head, 3¼ inches from the anterior midline (nasal bridge), and 3¼ inches from the left external auditory meatus, is an entrance gunshot wound. The central, circular, 0.9 cm diameter defect is circumferentially surrounded by a 0.1 cm wide pink abrasion collar. Radiating microtears (0.2-0.3 cm long) extend from the defect edges in the 8, 11, 12, 1, and 2 o’clock directions. The defect is centered within an 8 x 8 cm area of powder stippling of the skin that extends from the left cheek onto the inferior left forehead and from the left zygomatic prominence to the upper and lower lids of the left eye. The left globe is collapsed and proptic due to extensive injury of the orbital bones with injury to, and swelling of, the orbital contents. There is dark red-black drying of the exposed sclera and conjunctiva. The wound pathway continues through the bony structures of the left cheek/orbit (left zygomatic bone and orbital bones), the left orbital contents, the bony structures of the left anterior cranial fossa, the left frontal lobe of the brain, the optic chiasm and optic nerves, the midbrain, and the right occipital lobe of the brain. Jamar O'Neal Clark 15-6355 Page 6 The wound pathway through the brain is pulpified and hemorrhagic, containing multiple pieces of fragmented bone. A thin, diffuse layer of subarachnoid and subdural hemorrhage coats the cerebral convexities and base of the brain. Approximately 50 mL of loosely clotted subdural hemorrhage is over the right cerebral convexity. The cerebral hemispheres are diffusely swollen, with flattening of the gyri, narrowing of the sulci, and compression of the lateral ventricles. The cerebellar tonsils are swollen, softened, and tightly apposed to the brainstem. There is a comminuted, complex, eggshell fracture of all of the left anterior cranial fossa and medial right anterior cranial fossa bony structures, extending into the lesser sphenoid wing and medial aspect of the greater sphenoid wing on the left. The fracturing of the left anterior cranial fossa radiates into a 5 cm long linear fracture of the right side of the frontal bone, a 7 cm long linear fracture of the left parietal bone, and a 3 cm long linear fracture of the petrous ridge of the left temporal bone. A separate, hemorrhagic, 1 cm maximum dimension aggregate of hairline fractures is in the orbital roof of the right anterior cranial fossa. Four localized 0.4 to 0.7 cm maximum dimension foci (two right and two left) of hemorrhagic hairline fractures are in the squamous portion of each temporal bone, just anterior to the petrous ridges. There is multifocal hemorrhage in the frontal, superior, and right lateral scalp, confined to the periosteum and subgaleal connective tissue and in areas overlying or in continuity with the aforementioned bony injuries; incisions of these areas show no subcutaneous hemorrhage in tissue superficial to the aponeurosis of the scalp. All layers of the scalp are widely hemorrhagic and swollen on the left, in association with the gunshot wound and the related left anterior cranial fossa fractures. There is periorbital ecchymosis (5 cm maximum dimension) of the right eye. Recovered from the right occipital lobe of the brain, just right of the sagittal midline, is a 2.7 cm maximum dimension copperand lead-colored projectile. A 0.5 cm maximum dimension leadcolored metal fragment is recovered from the left temporalis muscle. The overall wound direction, relative to standard anatomic position, is front to back, slightly left to right, and slightly upward. Jamar O'Neal Clark 15-6355 Page 7 OTHER INJURIES: • A pair of obliquely oriented, linear, 3 and 1 cm long dried scratches is on the lateral aspect of the right arm. • A 1.5 cm long, obliquely oriented, dried linear scratch is on the lateral aspect of the distal left forearm. • A discontinuous line of vertically oriented scratches, 2.5 cm maximum dimension, is just left of the midline of the upper back. SOFT TISSUE DISSECTIONS: An incision is carried down the midline of the posterior neck and back to the right and left buttocks. Subcutaneous dissection of the neck, shoulders, back, flanks, and buttocks demonstrates no occult contusions. BACK: The anterior aspect of each distal forearm and wrist is vertically incised. Circumferential subcutaneous dissection demonstrates no occult contusions, or other injuries suggestive of restraint. Localized hemorrhage is encountered over the left radial artery, consistent with documented medical intervention. Two cutaneous macular scars on the posterior aspect of the left wrist are also incised, confirming absence of contusions. WRISTS: INTERNAL EXAMINATION: The brain weighs 1210 g. Coronal sections through uninjured parts of the brain demonstrate sharp demarcation between white and gray matter, without hemorrhage or contusive injury. The atlanto-occipital joint is stable.
