Already at a record low, the city's murder rate has taken a dip in the first half of 2013.
In almost six months, there have been 154 murders.
That's less than one per day, and down from 202 in the same period last year.
Police Commissioner Ray Kelly said the drop is largely thanks to the New York City Police Department's new anti-gang strategy, which fights retaliatory violence among rival gangs.
Other police officials credit efforts to stop violence by abusive husbands.
The drop comes as the police department faces criticism over its stop-and-frisk policy.
The mayor and police commissioner have cited stop-and-frisk as a big reason for the drop in crime.
Stops are actually down over the last year, so it's unclear whether this latest drop is a result of the long-term impact of stop-and-frisk or a product of other factors.
