A recent study has suggested the death toll from mass shootings in the United States was increasing.
The research, which was funded by the US Justice Department and released on Friday, indicated the upward trend of shootings in the country.
Study researchers, which analyzed all the mass shootings that took place between 1966 and 2019, found that suicidal intention was a "strong predictor" for mass shooting perpetrators.
About one-third of the mass shooters had experienced childhood trauma while 80 percent were "in crisis."
About half of the shooters also took steps to leak their plans in advance to family, friends, law enforcement or strangers.
"This study - one of the most extensive assessments of mass violence to date - reveals a deeply unsettling trend: more Americans are dying at the hands of mass shooters than at any point in recent history," said Amy Solomon, the Principal Deputy Assistant Attorney General for the Office of Justice Programs.
Meanwhile, US President Joe Biden on Thursday traveled to New York City to assert the Democratic Partyís support for the police and detailing his administrationís plans to work with the city to confront the surge in gun violence.
Biden announced actions for investing in policing and community intervention programs in response to the surge in gun violence in recent years.
The surge in gun violence has particularly impacted big cities across the US, including Americaís business capital, New York.
Since 2020 when the COVID-19 pandemic began, there has been a significant rise from 2019 to 2020, when murders rose by nearly 30 percent.
So far this year, 94 shootings incidents were reported in New York City, compared to 71 in the same period last year.
