Before the police enter Ruth Davenports room they call it in as a "possible 1054".
I googled that police code when police codes can vary from state to state I found "livestock on the highway" - that's removed link
However when you google 1054 - the first thing that comes up is the schism of removed link
Interesting when you think Ruth was actually cut in removed link
Quote from Britanica "Schism of 1054, also called East–West Schism, event that precipitated the final separation between the Eastern Christian churches (led by the patriarch of Constantinople, Michael Cerularius) and the Western Church (led by Pope Leo IX)."
Sorry about the "removed link" everywhere. Spam filter got out of control.
I don't think there's any one specific guide they're using for police codes. They rattle one off in the fourth episode that matches General Purpose list meanwhile 10-54 matches the Walnut Creek, CA listing.
