There are two numbers written in the cause of death portion of Henry Goldenstein’s 1921 death certificate from Kansas City, Missouri.
The 170 I understand–it’s the code for suicide by firearm.
The 167 I’m not certain I do understand. That code is for suicide by poisonous gas and all references to Goldenstein’s death (including his death certificate) indicate that he died as the result of a gunshot. That’s what the death certificate says as well “Suicide–Fire Arms.”
I’m not certain if the 167 is an error, a reference to contributory cause of death (which isn’t stated on the death certificate) or is simply an error.
Goldenstein’s family thought he was murdered. That would have changed the cause of death to a homicide, but the fire arm portion would have remained the same.
