New York City set a record Thursday after 10 consecutive days with no murders, according to Reuters.

The last time New York City saw a police rate close to that was in 2013 when the Big Apple had no murders for nine straight days.

The New York City Police Department recorded an all-time low murder rate of 328 in 2014.

"Everybody is behaving," NYPD Sergeant Daniel Doody said.

The number of arrests and court summonses plummeted in late December after officers expressed anger over the mayor's support for some of the NYPD's fiercest critics. Mayor Bill de Blasio has been struggling to fix the relationship between City Hall and the NYPD ever since.

New York City has been facing cold temperatures in the past days, which may have contributed the drop in murders. Doody said killings usually take place in the warmer seasons when more people are out in the streets and the hot weather makes them "cranky."

Murders were down 85 percent from its peak in 1990.

Police said much of the success in stopping murders has been because they target smaller groups that are responsible for most offenses.

Other big cities have seen a drop in violent crime in 2014, including Chicago which has seen the lowest amount of murders in 1965.

Experts say the murder rate is lower because of quick medical response. Reuters reported the number of shootings spiked by 13 percent at a time the murder rate hit a 50-year low on 2014.

"There continues to be better response times getting to the scene and getting people to the hospital so that shootings that previously would have ended in a fatality, won't," said Steven Messner, a criminal justice professor at the State University of New York at Albany.

New York City has struggled with its high crime rate mostly in the 1990s when more than 2,200 people were murdered in some rates.
