Had to be at least one female
Watch the video. The people who found the abandoned car opened all the doors and made video of the interior. Notice the following:
-- in the front, on the console, is a nice PINK mug.
-- On the back seat is what looks like a table (iPad ??) in a pink cover.
I don't mean to be sexist but the pink items suggest one or more ladies. (My 57 yr old daughter, who is a partner in a white shoe DC law firm has been all about pink since she got her first Barbie doll over 50 years ago -- Barbie was dressed in pink and she still has her collection of Barbies.)
-- Also -- look closely as the video pans across the windshield. In the top corner of the windshield on the passenger side there are some number written -- I can make out only 11 - _____. There is something written below that.
