I've heard several dispatches by Central County 911 when a person has died, but they normally just put it out in the dispatch as "obvious death" or "suspicious death law enforcement on scene/en route".
I'm just curious, but does Jeffco advise units to "respond on the quiet"? We get that alot in saint charles county. I was just curious, perhaps code D could mean "get there with the utmost quickness" or "take your time, no lights or sirens required".
Just a thought, hopefully someone in that area can figure it out.
