Subsequent to inquiries I made this morning, I received the following email from the Montgomery county Maryland public information office:
I searched our 911 call database for the above listed address. There was no call listed for 5/31, nor anything similar to what you described. I then searched each of our 6 districts for the entire day of 5/31 for a murder in progress, murder just occurred or murder occurred earlier call with negative results. I then spoke with our director to determine if this type of incident was brought to his attention recently and it was not. If your research proliferates any further detail that would help us to narrow down the search, please let me know. I can always check another address if you find one, but for the time being, I don’t see anything similar to what you described.
