Here you have the latest update about murder in the North-Central state of Carabobo. The chart shows murders per municipality month by month. Details for all municipalities are missing for April 2011, but we have the total for Carabobo in that month as well: 126 murders. Murder before 1999 was much lower and very seldom would reach 100 murders per month. December is almost always the bloodiest month.
Things differ a bit between municipios. Let's see Los Guayos, a municipality that was a calm village 30 years ago, with some grass and dusty fields and now is completely chock-a-block with shanty towns. Here again, the data for April 2011 is missing. Still, you can see a clear trend.
