INTERNAL EXAMINATION – SUMMARY

CENTRAL NERVOUS SYSTEM: The brain weighs 1,271 grams and is within normal limits. Hemorrhaging penetrates the skin and subdermal tissues of the neck.

MUSCULOSKELETAL SYSTEM: The hyoid bone is fractured. The remainder of the musculoskeletal system is intact, unremarkable, and within normal limits.

CARDIOVASCULAR SYSTEM: The heart weighs 254 grams and has an average size and configuration. Cardiac valves and coronary ostia are anatomic and unremarkable. No evidence of atherosclerosis or gross ischemic changes of recent or remote origin is present.

RESPIRATORY SYSTEM: The oral cavity shows no lesions. Petechial hemorrhaging is present in the mucosa of the lips and the mouth. Otherwise, the mucosa is intact, and there are no injuries to the lips, teeth, or gums. The mucosa of the epiglottis, glottis, piriform sinuses, trachea, and major bronchi are anatomic. The thyroid and the cricoid cartilages and the larynx are fractured. The lungs are unremarkable and weigh: right, 368 grams; left, 377 grams.

GASTROINTESTINAL SYSTEM: The mucosa and wall of the esophagus are intact and gray-pink, free from lesions or any type of injury. The gastric mucosa is intact and pink with the absence of injury. Approximately 21 ml of partially digested semisolid food is found in the stomach. The pancreas on section is uniform, gray-pink, and moderately firm. The mucosa of the duodenum, jejunum, ileum, colon, and rectum are intact and free from injury. Externally the small intestine, appendix, and colon are unremarkable.

HEPATOBILIARY SYSTEM: The liver weighs 1,211 grams. The gallbladder contains 2 cc of thick green viscid bile, no stones, and is grossly normal. The extrahepatic biliary system is unremarkable. The pancreas shows the usual lobular architecture and mild autolysis and is otherwise normal.

URINARY SYSTEM: The kidneys weigh: left 112 grams, right 103 grams. The kidneys are anatomic in size, shape, and location and are without lesions. The pelvic calyceal system and ureters are unremarkable. The bladder contained 3cc of urine. With this removed, the bladder wall is unremarkable.

FEMALE GENITAL SYSTEM: The structures are within normal limits. Examination of the pelvic area indicates the victim had not given birth. The inguinal regions and buttocks are normal. There are no indications of recent sexual activity.

TOXICOLOGY: A sample of the right pleural blood and bile are submitted for toxicologic analysis. Stomach contents are saved.

SEROLOGY: A sample of the right pleural blood is submitted in the EDTA tube. Routine toxicologic studies were ordered.

DESCRIPTION OF INJURIES - SUMMARY

(1) Multiple occurrences of acute blunt force trauma to the anterior of the neck resulting in extensive injuries to the larynx, thyroid, and cricoid cartilages. The initial blow was administered to the left side of the neck. Ensuing blows were delivered in quick succession to the left, center, and right sides of the neck.

It cannot be determined which was the fatal blow, though several of the estimated eleven strikes were potentially lethal.

The instrument used to deliver these blows is approximately 1 cm in diameter, with rounded edges and a smooth surface.

Opinion: These are fatal injuries.

(2) There are oblique and transverse fractures with varying displacements of the middle and proximal phalanges on the left hand. Contusions are present on the left and right hands and forearms. These injuries are consistent with defensive wounds.

Opinion: These are non-fatal perimortem injuries.
