CHICAGO — Chicago has logged its 500th homicide of 2012.

The last time the city reached the 500-homicide mark was in 2008, when the year ended with 512 killings. Last year, city records show Chicago had 435 homicides.

On Thursday, officials with the Chicago Police Department said the city was one homicide away from the 500 mark. Hours later, a 40-year-old man was fatally shot in the Austin neighborhood on the city's West Side. Police say Nathaniel Jackson was found on the sidewalk outside a convenience store with a gunshot wound to the head late Thursday.
