Lets see,  43 incidents.   Assuming each resulted in one fatality, 43 fatalities.  According to the CDC there were some 1500 children (0-4 yo) killed by unintentional suffocation in 2015.  Unintentional drowning killed another 400.  Homicide killed another 285.  You have to parse down to Homicide-Intentional Suffocation to get down to similar numbers  (53 for Intentional Suffocation,  43 for accidental gunshot wound).  Or Homicide Firearm for 50.  https://www.cdc.gov/injury/images/lc-charts/leading_causes_of_injury_deaths_violence_2015_1050w760h.gif
