“Seven victims were shot and we’ve now confirmed that three were deceased,” Rochester police chief Michael Ciminelli told reporters at the scene, NBC reports.

The victims, all men, are believed to be between the ages of 20 and 29. Their names have not yet been release though none suffered life-threatening injuries, Ciminelli says.

Hundreds of people were at the scene when Lauren Petracca, a photographer for the Democrat and Chronicle, arrived to take pictures for the paper.

“I could hear people screaming and crying,” Petracca, told NBC. “A mother of one of the victims arrived and collapsed on the ground screaming, ‘No, no, no!’ These are sounds I won’t forget.”

Ciminelli vowed to go after the person or persons responsible.

“We are bringing every resource that we have at our disposal to bear on this and we will run this down and find out who did this,” he says, adding: “This was an outrageous act.”
