“Last night was a very tragic night for our community,” Buffalo Police Commissioner Joseph A. Gramaglia said at a news conference Saturday.

Gramaglia said the shooting was not related to the family reunion.

“It was a warm night with a lot of people outside, and the gunshots had nothing to do with the gathering,” he said. “These children were just enjoying a summer evening when tragedy struck.”

“A 3-year-old child on his tricycle, having fun with his family members on a hot summer night, his 7-year-old big sister by his side, and out of nowhere gunshots ring out. And the children are being hit by gunfire,” said Buffalo Mayor Byron Brown.

Gramaglia praised the speed with which officers responded to the shooting, saying they arrived on the scene “very quickly.”

According to Erie County Prosecutor Michael Keane, the mother of the two children is a well-known member of the community who is active in Most Valuable Parents, a local organization focused on improving safety in Buffalo.

“She is a strong woman, who constantly works with other families to keep our children safe,” he said. “And now this tragedy hits his own family.”

Police have not said whether one or more persons of interest have been identified as of Sunday afternoon and are encouraging anyone with information about the shooting to come forward.

A weapon found at the scene is currently being tested, police said.

“We need the community to come together and help us stop this violence,” Gramaglia said. “Our hearts go out to these children’s families and we will do everything in our power to see justice for this senseless act.”
