The parking at the doubletree is garaged / controlled access.
If Jack's car had been moved there would been a record and
video of the event.
From that link there’s a witness who says
“Kathleen Boyer, a security guard at the New Castle County Courthouse, said a man she now believes was Wheeler told her he was dropped off by his brother two days prior so he could visit his mother, in Wilmington. The man did not have any apparent injuries but did mention he was robbed of his briefcase. He was looking for a hotel and wanted to know where Front Street was.”
Front Street is where the Amtrak station is - more curious.
