Louisville Metro had fewerviolent and property crimes committed in 2012 compared to 2011,but Police Chief Steve Conrad is still concerned.One reason is an increase in homicides and aggravated assaults despite decreases in the other crime categories. Conrad told me earlier this week that trends from 2012 appear to be holding in 2013 through at least July.So let's look at the homicide numbers. Conrad noted that 39 homicides had happened in Louisville Metro Police's jurisdiction in 2013. That number appears to have increased by one since then.Here's a map showing where homicides have happened:By this point last year, Louisville had 44 homicides.
