The only reason I think it's fair and on topic here to discuss how streets are referred to in NYC is in trying to decipher the meaning of the text.
Queens is different than the other boroughs. In the city, which is what New Yorkers call Manhattan, lower Manhattan is from Colonial times and has its own geography and place names (Wall St, Water St, Maiden Lane etc). Above that is mainly a grid. If you were going to meet someone in midtown, say Lexington Ave and E. 34th St., you'd say "Lex and 34th."
But even though I've lived in NYC all my life, I get lost in Queens. My aunt and uncle used to live on 75th Ave. in Queens, but there's also a 75th St. and a 75th Road, and not always near each other, and before GPS I was always lost. You have to be specific in Queens because the numbered streets often have street, avenue and road. But Austin St. was near their home and it was always called Austin Street.
What I find odd about the text is the part that says "near Austin St. in Forest Hills." Even though you have to be specific in Queens, Austin St. already means Forest Hills. That sounds to me like someone who was in her life long ago, and trying to jog her husband's memory.
If OG was indeed having an affair, or had had one in the past, I have to say I feel so terrible for her husband. Whether or not she was murdered by the affair guy, that has to be a gut punch for the husband with no way to ask her about it. Unless it's old news and he forgave her.
As far as sleeping through what would be screaming and struggling, in my family we are two halves. Half of us, including me, will wake up if a feather drifts a mile away. The other half doesn't wake up even with the type of alarm clock that shakes the bed and makes a piercing noise. A 13-year old several stories above the basement, probably listening to music or playing a video game, I can absolutely understand him not hearing anything.
Just to comment on things that have been mentioned, someone thought the murderer may have wanted the dog, but I didn't see any sign of a dog in the video. And as for OG being Hungarian and Putin got her somehow, unless she was some high-level spy who went rogue, she wouldn't be on his radar. There are a lot of Russians, Ukrainians, Georgians and others around here, who left their countries years ago. I cannot see this at all.
The person in the video was walking very briskly, which made me think he's young. Not necessarily a teenager. I could see a scenario though where a friend of either of the sons was maybe banned from their home, a bad influence or something, and that person might have taken revenge.
Who knows. We will know when we are told.
An irredeemable tragedy all around.
