An aspiring rapper and his manager were fatally shot in Manhattan early Sunday, part of a bloody weekend in which 13 others also were wounded by gun violence, authorities said.

Police believe that rapper Francisco Mercedez, 29, and manager Kenny Jimenez, 21, were targeted in front of a deli on Broadway near West 155th Street in Harlem at around 3 a.m.

They were gunned down by a man in a white sedan, a witness said, after returning from a record-release party in Connecticut.

The night before, a man shot three teens at around 10 p.m. in East Harlem’s Jefferson Park. Hours later, in Morningside Heights, a man was shot in the arm at around 1:20 a.m. near St. Nicholas Avenue and West 127th Street, police said.

In The Bronx, three men were shot at East 137th Street and Brook Avenue at around 3:10 a.m., cops said.

Three hours later in Jamaica, Queens, four partygoers were shot on 118th Avenue when a man opened fire on the group.
