(snipped by me)
Not really any vacant houses. It's an average middle-class neighborhood. There IS quite a bit of construction just a little way down on 84th Street though. That would be a good place to hide. Construction also seems like it could be the kind of place you could get stuck.
The thing is, he was seen on camera at the corner of 84th and Harrison. That is a major intersection. There is almost no pedestrian traffic there, so I really feel like someone would have seen him if he tried to cross the street. It would have stood out. That goes for anywhere along 84th, Harrison, Giles, or 72nd St. They're all busy and you'd almost have to cross at a corner... unless he crossed at night. If he was just wandering down the street, someone would have seen him... even at night. If he went through a neighborhood, someone would have seen him or have video of him. People have cameras and those Ring things. There's no way he would've been able to just disappear like he did.
I don't want to say it, and I'm sure LE has thought of it (and probably checked), but I really hope he didn't hide in a dumpster.
