No it shouldn't. That's a ONE year increase, not part of a larger trend. In fact it goes against the trend of the murder rate decreasing since the 1990s.  Remember one, two or even three years does not make a trend.  It's normal in areas with relatively few murders like Hawaii to see fluctuations in the year to year numbers. Now if murders increase continuously over the next 5 years, it should be the gist of the story.
