Three people were shot – two fatally – in separate overnight incidents across the city, cops said.

A 39-year-old man was found with a mortal gunshot wound to the chest, sitting in the front driver’s seat of a parked car on West 135th Street near Riverside Drive in Harlem around 6:20 p.m. Sunday, cops said. 

He was rushed to Mount Sinai Morningside, where he was pronounced dead. 

No arrests have been made in connection to the slaying, and the motive remained under investigation Monday morning. 

The victim was not immediately identified, pending family notification, cops said.

A few hours later, Richard Reed, 35, was shot multiple times inside a building on Sands Street near Navy Street in Downtown Brooklyn, part of NYCHA’s Farragut Houses, cops said.

Reed – who lives in a different building within the housing complex – was repeatedly blasted in the chest in the lobby around 10 p.m., police said.

He was rushed to Brooklyn Methodist Hospital, where he was pronounced dead.

No arrests have been made, and the investigation is ongoing.

The violence continued around 3 a.m. Monday, when a 42-year-old man was shot twice in the Bronx, cops said.

The victim was blasted once in the torso and once in the left arm on East 180th Street near Third Avenue in the Belmont neighborhood, police said. 

He was taken to St. Barnabas Hospital with non-life-threatening injuries, authorities said. 

A male suspect, last seen wearing a white vest, fled east on East 180th Street, cops said.

No arrests have been made, and the motive for the violence was not immediately known.
