Just as an aside, most police codes aren’t really standardized across different agencies.

There’s a handful of 10-codes that are pretty much universal, like “10-4”

67 isn’t one of those codes. A lot of departments do use it for a report of a death

But it’s also commonly used to advise of an important incoming message

And other agencies may have other uses for it

And other agencies use other systems besides 10 codes, I believe some departments in CA have been known to use penal code numbers

But so because of that, there’s been a big movement in emergency service to use plain language over codes for the last decade or two, mostly since Katrina since different agencies using different codes lead to a lot of miscommunication there.

I work in 911 dispatch, at my agency and pretty much everywhere around me it’s all plain language. One or two 10-codes linger around, more as informal slang than anything that gets official use. 10-4 sometimes gets used, but that’s practically just part of the English language now.

10-96 also kind of lingers around in my agency, which in the set of 10-codes they used before I started was for a subject with mental health issues. We’re not really supposed to use it but no one has really come up with a better shorthand for it so it still pops up from time to time, mostly from our officers.
