Seven people died while four others were wounded in a number of shootings across New York City over the weekend.

The bloodshed began on Saturday around 5:40 p.m. in Brooklyn when a 36-year-old man, identified as Yasser Julio, was fatally shot in front of a dry cleaning business in Flatbush-Ditmas Park.

Yasser's brother, Pedro Julio, told The New York Times that his brother was a "family-oriented man" and the father of two sons. "It doesn't feel real," he added.

About two hours later, gunfire erupted on East Tremont Avenue in the Bronx, killing 25-year-old Nestor Suazo and leaving a 34-year-old woman with critical injuries. Both victims suffered from gunshot wounds to the torso.

Later that night, a 34-year-old man was shot in East Harlem around 10:40 p.m.

The gun violence spilled into Sunday, when three men were fatally shot just before 2 a.m. in the Ingersoll Houses in Fort Greene, Brooklyn. One of the victims was 76 years old.

"I heard eight shots. Boom, boom, boom. It was really loud," Daniel Alty, 21, a resident at the public housing complex, told The New York Daily News. "I got out of my bed and laid down on the floor to be safe. I was scared to look out the window."

The last homicide occurred on Sunday at 2:49 p.m. when David Hooks, 24, was fatally shot in the Fordham section of the Bronx. He died at the St. Barnabas Hospital. Police have yet to determine a motive.

The gunfire spike marked a fivefold increase in the city's weekly murder rate compared to last year.

Still, NYC Mayor Bill de Blasio told reporters on Sunday that he is "confident that the N.Y.P.D. is going to find the perpetrators."

The mayor added that the shooting at the Ingersoll Houses "appears to be criminals against criminals. That doesn't mean we take it less seriously. But we've put a lot of money into Ingersoll and other housing projects, and we're not going to let this situation stop us from continuing to drive down crime," he said.
