External examination
The investigator must carefully examine the body for potential
evidence, injuries, and disease in order to preserve evidence
and alert the pathologist to the need for autopsy; most
important function of the MDI; head to toe examination is most
common
Head examination
-SCALP: examine the scalp for hidden trauma, account for any
blood that's been identified
-EARS: inspect the ears for hemorrhage or foreign bodies
-EYES: evaluate the eyes for petechial hemorrhage, icterus
(jaundice), or hemorrhage
-MOUTH: inspect the oral cavity for trauma, foreign bodies, or
poor hygiene
-NOSE: inspect the nasal septum for perforation due to chronic
cocaine abuse
Neck
-View the posterior neck
-Examine for large lymph nodes, thyroid, and/or masses
-Palpate the neck with passive flexion and extension to reveal
fx
-Do not recover specimens from the neck veins of homicide
victims; may create trauma
, Chest
-Examine the dimension of the chest
-Document the anterior/posterior size
-An enlarged, barrel-shaped chest is a sign of chronic lung
disease
-Palpate the breasts for any masses
Abdomen
-Palpate the abdomen to detect the presence of fluid or
masses; excessive fluid may represent liver cirrhosis or failure
-Document any surgical incisions
External genitalia
-Examine for masses, ulcerations, surgery, or circumcision in
males
-Examine for prolapse of the uterus, masses, trauma, and
ulcerations in females

-Review the symmetry of the limbs
-Fxs of the hip are usually indicated by the shortening and
external rotation of the limbs
-Look for trauma, fxs, burns, and scratches

suggestive of CHF
