"Homicides" or "natural" causes
Conclusion
The literature has been traced on the rate of covert homicide in SIDS, whether for a single death or in multiple deaths. The use of a percentage – e.g., the notion that 10% of SIDS are homicides – is problematic because the rate of sudden death in infancy has fallen, making percentages less valuable. The developing literature suggests that the initial figures were overestimates. The rate of homicide was based upon opinion and the evidence has been called uncontrolled, circumstantial, anecdotal, and indirect. However, the literature is clear that some sudden deaths in infancy are covert homicides, though the percentage is low. Similarly, whether multiple cases of SIDS are all homicides or could be from natural causes remains controversial. The different approaches to this problem may also reflect jurisdictional differences. For example, medical examiners certify manner, but some forensic pathologists in a coroner's system do not. Some may also have been influenced by such philosophical approaches to infant death investigation as “think dirty”, an approach that was promulgated in Ontario (33).
