Marty played the possible 911 calls from Sally and a neighbor. The Sally call definitely sounds like someone doing an impersonation. Like it sounds vaguely like her, but not exactly.
The neighbor call is more interesting, imo. It says it's from 336, and says police have been called the exact 113 times. If the Sally call wasn't a confirmed fake, I would just chock it up to coincidence that the neighbor who lives in a house that's censored on Google maps just happens to call. But my autistic brain sees it as a connection. I think it's fake, too.
