HARLEM, Manhattan (PIX11) — Following a Buffalo mass shooting Saturday, New York City Mayor Eric Adams promised to “pray and work to end the scourge of gun violence and hatred that has terrorized our country.”

Monday night, he followed up on one of those promises by participating in a vigil for the 10 victims. The vigil started 8 p.m. at Bethel Gospel Assembly in Harlem.

Adams arrived later because he was visiting with the family of a drive-by shooting victim in the Bronx. At the vigil, he said a staffer told him that the 11-year-old girl died. Police did not confirm as of 9:38 p.m.

Adams said drew comparisons to violence both in New York City and Buffalo.

“I must protect the innocent people of this city,” he said.

Other officials, including New York Attorney General Letitia James, were also in attendance.

“We’ve come together in deep pain,” James said, “but with purpose. We are in pain for the 13 individuals who were shot and the 10 beautiful lives that were lost.”

She said, after praying, people “must demand responsible gun laws in our nation.”

Ten people were killed and three others suffered non-life-threatening injuries after a mass shooting at a supermarket on Buffalo’s East Side Saturday afternoon.

Payton Gendron, 18, allegedly traveled about 200 miles from his home in Conklin, New York, to Buffalo to commit the attack, police said. According to officials, Gendron researched the local demographics and arrived in the area a day in advance to conduct reconnaissance with the “express purpose” of killing as many Black people as possible.

“It was a racially motivated hate crime,” Gov. Kathy Hochul said.
