CLINICOPATHOLOGIC CORRELATION: Cause of death of this six year old female is asphyxia by strangulation associated with craniocerebral trauma.
The body of this six year old female was first seen by me after I was called to an address identified as 755 - 15th Street in Boulder, Colorado, on 12/26/96. I arrived at the scene approximately 8 PM on 12/26 and entered the house where the decedent's body was located at approximately 8:20 PM. I initially viewed the body in the living room of the house. The decedent was laying on her back on the floor, covered by a blanket and a Colorado Avalanche sweatshirt. On removing these two items from the top of the body the decedent was found to be lying on her back with her arms extended up over her head. The head was turned to the right. A brief examination of the body disclosed a ligature around the neck and a ligature around the right wrist. Also noted was a small area of abrasion or contusion below the right ear on the lateral aspect of the right cheek. A prominent dried abrasion was present on the lower left neck. After examining the body, I left the residence at approximately 8:30 PM.
EXTERNAL EVIDENCE OF INJURY:
Wrapped around the neck with a double knot in the midline of the posterior neck is a length of white cord similar to that described as being tied around the right wrist. This ligature cord is cut on the right side of the neck and removed. A single black ink mark is placed on the left side of the cut and a double black ink mark on the right side of the cut. The posterior knot is left intact. Extending from the knot on the posterior aspect of the neck are two tails of the knot, one measuring 4 inches in length and having a frayed end, and the other measuring 17 inches in length with the end tied in multiple loops around a length of a round tan-brown wooden stick which measures 4.5 inches in length. This wooden stick is irregularly broken at both ends and there are several colors of paint and apparent glistening varnish on the surface. Printed in gold letters on one end of the wooden stick is the work "Korea". The tail end of another word extends from beneath the loops of the cord tied around the stick and is not able to be interpreted. Blonde hair is entwined in the knot on the posterior aspect of the neck as well as in the cord wrapped around the wooden stick. The white cord is flattened and measures approximately 1/4 inch in width. It appears to be made of a white synthetic material. Also secured around the neck is a gold chain with a single charm in the form of a cross.
A deep ligature furrow encircles the entire neck. The width of the furrow varies from one-eighth of an inch to five/sixteenths of an inch and is horizontal in orientation, with little upward deviation. The skin of the anterior neck above and below the ligature furrow contains areas of petechial hemorrhage and abrasion encompassing an area measuring approximately 3 x 2 inches. The ligature furrow crosses the anterior midline of the neck just below the laryngeal prominence, approximately at the level of the cricoid cartilage. It is almost completely horizontal with slight upward deviation from the horizontal towards the back of the neck. The midline of the furrow mark on the anterior neck is 8 inches below the top of the head. The midline of the furrow mark on the posterior neck is 6.75 inches below the top of the head.
The area of abrasion and petechial hemorrhage of the skin of the anterior neck includes on the lower left neck, just to the left of the midline, a roughly triangular, parchment-like rust colored abrasion which measures 1.5 inches in length with a maximum width of 0.75 inches. This roughly triangular shaped abrasion is obliquely oriented with the apex superior and lateral. The remainder of the abrasions and petechial hemorrhages of the skin above and below the anterior projection of the ligature furrow are nonpatterned, purple to rust colored, and present in the midline, right, and left areas of the anterior neck. The skin just above the ligature furrow along the right side of the neck contains petechial hemorrhage composed of multiple confluent very small petechial hemorrhages as well as several larger petechial hemorrhages measuring up to one-sixteenth and one-eighth of an inch in maximum dimension. Similar smaller petechial hemorrhages are equally dilated. The sclerae are white. The nostrils are both patent and contain a small amount of tan mucous material. The teeth are native and in good repair. The tongue is smooth, pink-tan and granular. No buccal mucosal trauma is seen. The frenulum is intact. There is slight drying artifact of the tip of the tongue. On the right cheek is a pattern of dried saliva and mucous material which does not appear to be hemorrhagic. The neck contains no palpable adenopathy or masses and the trachea and larynx are midline. The chest is symmetrical. Breasts are prepubescent. The abdomen is flat and contains no scars. No palpable organomegaly or masses are identified. The external genitalia are that of a prepubescent female. No pubic hair is present. The anus is patent.

Skull and Brain: Upon reflection of the scalp there is found to be an extensive area of scalp hemorrhage along the right temporoparietal area extending from the orbital ridge, posteriorly all the way to the occipital area. This encompasses an area measuring approximately 7 x 4 inches. This grossly appears to be fresh hemorrhage with no evidence of organization. At the superior extension of this area of hemorrhage is a linear to comminuted skull fracture which extends from the right occipital to posteroparietal area forward to the right frontal area across the parietal portion of the skull. In the posteroparietal area of this fracture is a roughly rectangular shaped displaced fragment of the skull measuring one and three-quarters by one-half inch. The hemorrhage and the fracture extend posteriorly just past the midline of the occipital area of the skull. This fracture measures approximately 8.5 inches in length. On removal of the skull cap there is found to be a thin film of subdural hemorrhage measuring approximately 7-8 cc over the surface of the right cerebral hemisphere and extending to the base of the cerebral hemisphere. The 1450 gm brain has a normal overall architecture. Mild narrowing of the sulci and flattening of the gyri are seen. No inflammation is identified. There is a thin film of subarachnoid hemorrhage overlying the entire right the entire right cerebral hemisphere. On the right cerebral hemisphere underlying the previously mentioned linear skull fracture is an extensive linear area of purple contusion extending from the right frontal area, posteriorly along the lateral aspect of the parietal region and into the occipital area. This area of contusion measures 8 inches in length with a width of up to 1.75 inches. At the tip of the right temporal lobe is a one-quarter by one-quarter inch similar appearing purple contusion. Only very minimal contusion is present at the tip of the left temporal lobe. This area of contusion measures only one-half inch in maximum dimension.
The cerebral vasculature contains no evidence of atherosclerosis. Multiple coronal sections of the cerebral hemispheres, brain stem and cerebellum disclose no additional abnormalities. The areas of previously described contusion are characterized by purple linear streak-like discolorations of the gray matter perpendicular to the surface of the cerebral cortex. These extend approximately 5 mm into the cerebral cortex. Examination of the base of the brain discloses no additional fractures.
Neck: Dissection of the neck is performed after removal of the thoracoabdominal organs and the brain. The anterior strap musculature of the neck is serially dissected. Multiple sections of the sternocleidomastoid muscle disclose no hemorrhages. Sections of the remainder of the strap musculature of the neck disclose no evidence of hemorrhage. Examination of the thyroid cartilage, cricoid cartilage and hyoid bone disclose no evidence of fracture or hemorrhage. Multiple cross sections of the tongue disclose no hemorrhage or traumatic injury. The thyroid gland weighs 2 gm and is normal in appearance. Cut sections are finely lobular and red-tan. The trachea and larynx are lined by smooth pink-tan mucosa without intrinsic abnormalities.
