I thought she said "half-hour." Supposedly the time the police got to Buchanan 12:55 a.m. to the security guard calling 911 at 1:22 a.m. (27 minutes or so).
I heard the Greta conversation.
He said the events at Kroger happened around 2:00. He said there was about an hour between leaving 610 N Buchanan and the Kroger event.
This is clearly false, this guy knows less than Freepers do about the timeline.
