I wish the police would divulge a little more information about the timeline. I think they know how the killer got from Dani's apartment back to Met Life to pick up his car, and when—they were onto him so fast that they must have been able to piece together his movements from security footage, cell phone pings, witnesses, etc.
I don't remember the details, but I remember someone on here mentioning a specific dumpster near an apartment building (possibly near Hines Park?).
By the way, do we know where the perp's car was parked during the Hines Park attempted rape? If that was his one of his hang-out spots, then any dumpster in view of that location should be considered.
