>>There is about a one-minute gap during which police say they’re not sure what happened.<<
Well I’m not sure why the Police didn’t know. They were on the phone with Zimmerman when he said that he was watching a man, then said that he was pursuing him, then said “I lost him” THEN sat on the phone giving his position and asking that the police call him when they arrive so he could tell them where he was at that moment.
Maybe the Orlando Sentinel didn’t listen to the actual 911 tape. Maybe the police rep who gave that statement didn’t. I don’t know, but I do know that when you search for the call, and look at the time at the bottom of the file, it was much more than a minute.
