This report (post above) of 5th and King is a completely different address than what I’ve seen up to this point - unless it’s the video the police haven’t released.
Colonial parking has quite a few structures in the area
Btw, the man I mentioned earlier today, who disappeared on Dec 29 on his way home, lives right across the street from the Cool Spring Reservoir, shown at the top left of the map you linked to in post 561. Within walking distance of the Hotel DuPont/Nemours Building/Law Offices of Connolly Bove Lodge & Hutz LLP.
The video where he is holding his shoe is at the courthouse parking garage at 5th and King. That's why he interacted with courthouse employees (the Court address is 500 King St) I've been there several times. The way it works, you get a ticket on the way in. When you are leaving, you put your parking ticket into the machine and it tells you the amount, which you pay (I have always used credit card), and then you have 10 minutes to get to your car and exit.
And yes, Colonial has parking areas all over the region.
You were asking about the DoubleTree report. Philly.com (Philly Inquirer/Daily News) and other news outlets were reporting on Jan 5 that his car was found at the DoubleTree. For example, here's Will Bunch's report, which states: "Authorities said that Wheeler's car turned up later at a different parking lot, at the DoubleTree Hotel in Wilmington."
Hope this info helps!
