To bad there is nothing to report after 3 days  --  shooting was a week ago tonight.   How about asking the Safeway parking lot witnesses if any one from the police or troopers has contacted them.   How about asking the troopers how the investigation is going.   How about asking the Chief whether he reviewed the video cams before handing them over or did he just keep a copy for the City lawyers.  Could ask the Mayor if the City is satisfied with the progress of the investigation.
Come on Lisa D  ---  after a week of official nothing why not write a story repeating the only information you were able to get.  If you have asked any reasonable questions and didn't get an answer that's news you can and should report.  Maybe the City attorney would be willing to be quoted as saying "We have no comment related to the Safeway parking lot death a week ago".
I'm reminded of Hogan's Hero's guard Shultz saying "I know nothing".
