The incident happened just after 1:45 p.m. at East 198th Street and Pond Place.
Police sources say 40-year-old Kavon Reid, of Yonkers, was shot in his back in front of a senior home.
The bullet went through Reid's chest and through his heart. He ran for one block and collapsed on Bainbridge Avenue.
The suspect fled south on Pond Place.
Police sources say Reid and the suspect had no interaction prior to the shooting, but that the suspect recognized Reid after he walked by him.
"He walked over here across the street, and I heard 'pop, pop, pop.' So, he runs back to me and says 'yo, I got shot,'" one witness said. "He got shot in the leg and the lower part of his chest, and he passed out right there by the bus stop over there. When I turned around to try to help him, I saw him in convulsions and vomit coming out his mouth, so I couldn't help him, so I just called the police."
Reid was transported to St. Barnabas Hospital where he was pronounced dead.
The suspect is described as a man wearing a grey-hooded shirt and a face mask.
Investigators have video of the shooting, but there's no word yet on a motive.
No arrests have been made.
