Telling the difference between ‘suicidal and homicidal’ injuries is the subject of this JFS article from 2014. Determination is not certain by any means. A recent, yet unpublished, study by the National Association of Medical Examiners (NAME) is also focused with this subject. The study was managed by Robert Oliver MD who found little reliability in examiner agreement. Sources say he is looking into a do-over.
From the JFS article:
“However, the differential diagnosis can be difficult and may even be impossible on rare occasions , even with previous experience with such cases . In some cases, many of the factors reputedly indicative of self-infliction can be absent, while elements more typical of homicide are present [9-12].”
