It's a trend police departments have noted from East Coast to West, even as other violent crimes such as aggravated assault and non-violent crimes such as burglary decline in the same areas.
"It's definitely worse this year, for us at least," Rochester Police Department Public Information Officer Carlos Alvarado told Fox News Digital of the upstate New York city's homicide numbers for 2021.
Rochester had seen a record 80 homicide deaths in 2021 as of Tuesday. The city's previous record was 69 in 1991, Alvarado said, adding that the number will "easily" be higher than 80 before the new year.
But Rochester isn't alone. At least 15 other cities have experienced record homicide rates this year, including some cities that surpassed their record-setting years of 2020.

Lisa Dadio, a former lieutenant from the New Haven Police Department and assistant dean and director of the Center for Advanced Policing at the University of New Haven, says experts initially linked rising violent crime in 2020 to the pandemic. But as the deadly violence has persisted into 2021, experts are looking deeper for more answers.
"When [crime] started spiking, myself and many others thought it had to do with the pandemic," Dadio said. "People were cooped up and lost jobs and … the psychological toll that the pandemic had on everybody — everybody was affected. … And I definitely think that that's a piece of it, but I think we're at that point now where it's much bigger than that."
In Connecticut, life has gone back to "quasi-normal" after the pandemic, but violent crime is "continuing," Dadio said.
"In fact, in many ways, certain things have skyrocketed. People seem to be less tolerant and less patient and are becoming more aggressive — whether it's driving on the road or checking out at a store. I think it comes back to kind of what we all felt for such a long time with the pandemic," she said.
She added that the areas where a lot of violent crime is rising "tend to be pretty sequestered to a particular part of" a city, where neighborhood conflict is more frequent and often "has to do with narcotics."
On top of those issues, the pandemic has taken a big toll on the criminal justice system in general, with backlogged criminal cases, reduced prison populations, remote court appearances and reduced sentences.
"They're letting people go," Dadio explained, "because of the pandemic and staffing and … it's such a complicated system that it's not just the crimes being committed. … Every process is so delayed now. So, you have people who have been arrested for offenses that are still out there because their case hasn't been adjudicated yet. I'm not saying that they should or should not be incarcerated, but they need due process."
