The point of the post was that it was first time I'd considered the selfie could have been taken inside a car, instead of in someone's house (unknown specifics in both cases, bf being unsure where it was taken, but not totally familiar background, which is why he said "looked like it was taken indoors"). LE asked Mollie's mom if she could confirm whether Mollie was "in a house" at 9:45 pm (15 minutes before Dalton opened the last snapchat photo from Mollie).
Did she take that last selfie in her bf's house, someone else's house, or in her car or someone else's car? LE hasn't said whether they narrowed that location down.
