CHICAGO • Authorities say Chicago could close out 2014 with the lowest number of homicides in decades.

The Chicago Police Department reported 390 murders through Dec. 20. That's according to a story published Saturday in the Chicago Sun-Times.

The last time the numbers were in the same range was in 1965 when the total was 397. The newspaper reports that 2014 is at least a 2 percent decrease from 2013. In 2012 there were over 500 killings.

The number is far less than the early 1990s when annual homicides in Chicago topped 900 at times.

Experts say crime overall has been declining.

The police department's count differs from the Cook County medical examiner's tally of 410. Police use federal guidelines in counting homicides and determined some were accidents or in self-defense.

While the number of homicides appears to trending lower in Chicago, murders are climbing in the city of St. Louis.
