LE said 4th. Around that area. Then went on to say the POI was parked somewhere around the mall, people had to have seen him. I later thought it was the north blocks of 4th but I don't recall if that came out in a later presser or an article, sorry.
ETA: I know LE had his car on video leaving the area so I assume they know approximately, if not exactly, where he parked. I hope they have video of Hannah getting in the car. And to keep his defense attorney from claiming he just gave her a ride and doesn't know what happened after that, I really pray LE has his car on video near Walnut Creek Park.
LE has never specifically said they have his car on video. The quote was from Mooney 'we have them leaving Tempo together' which implied several times to be from witness testimony. It is in the press conference.
