Abstract

Muscular hemorrhages around the scapula that are caused by upper extremity motion are rarely reported in cases other than drowning. We examined differences in the frequency of muscular hemorrhages around the scapula and stratified them by the cause of death. Muscular hemorrhages were mostly noted in cases of drowning (118/185, 63.8%), followed by cases of asphyxia (23/44, 52.3%). In addition, muscular hemorrhages around the scapula were found in cases of ligature strangulation (8/11, 72.7%), manual strangulation (2/3, 66.7%), choking (11/14, 78.6%), and traumatic asphyxia (2/2, 100%). Muscular hemorrhages were not found in cases of hanging or environmental suffocation, possibly because of the short time interval preceding the loss of consciousness. The distribution of muscular hemorrhages was similar in choking and drowning cases. Muscular hemorrhages due to strangulation were mainly unilateral, whereas those due to choking and drowning were mainly bilateral. During all types of asphyxia, muscular hemorrhages around the scapula were considered to be the result of conscious, active upper extremity motion. Because the frequency and laterality of muscular hemorrhages around the scapula differed based on the type of asphyxia, our findings provide insights into the manner of asphyxia that could be used to aid in the identification of homicidal hangings.
