Photo of the Day: Detectives Ben Brown and Billy Watts, along with crime scene techs, scoured the scene of a double homicide in February 2013. In this photo, I captured Brown and two techs inspecting a knife that may, or may not, be coated in blood. "Someone brought a knife to a gunfight," Brown said. Have attached relevant passage from book. More on book here: http://amzn.to/1UOfeE0
