text:  Friday frustration in the courthouse in Dedham, Massachusetts. Jurors tell the judge in the Karen Reid murder trial they've been unable to reach a verdict in their fourth day of deliberating whether Reid ran over her Boston police boyfriend in her SUV and left him to die in the snow or was he beat up in a boozy fight on an officer's night out and it was covered up. The judge tells jurors to keep deliberating. I'm Therese Crowley. This is Fox News.
