CHICAGO — One of the most violent years in Chicago history ended on Sunday with a sobering tally: 762 homicides, the most in two decades in the city and more than New York and Los Angeles combined.

The nation’s third-largest city also had 1,100 more shootings than it did in 2015, according to statistics released by the Chicago Police Department. The numbers underline a story of bloodshed that has put Chicago at the center of a national dialogue about gun violence.

The data released on Sunday is staggering, even for those who followed the steady news accounts of weekends ending with dozens of shootings and monthly death tolls that had not been seen in years. The increase in homicides from 2015, when 485 were reported, is the largest in 60 years.

Local news reports said that three people were killed and that 15 were wounded within the first six hours of the new year. In total, four people were killed and 24 were wounded in separate shootings on New Year’s Eve and into early Sunday, The Chicago Tribune reported.
