The devastated dad of a 9-year-old Bronx boy killed in the Dominican Republic posted tributes online to his slain son in a series of heart-wrenching social media posts.

Gioser Luís Feliz took a bullet to the head after leaving Santiago’s Cibao International Airport Wednesday while on a spring vacation with his father.

The child was gunned down as part of a robbery gone wrong — allegedly planned by a longtime family friend who preyed on the pair on their first trip to the country, according to police.

Tomás Peña Morel, 32, was among six men busted in connection to the shocking slaying.

He is alleged to have plotted the botched robbery.

Gioser’s father, Sergio Luis Feliz Mancebo, posted a series of pictures of father and son on his Instagram, including one with a broken heart emoji and one with the boy wearing a backpack.

Another shot appears to be a montage of images of the boy from a Friday night wake in the Dominican Republic.

“I love you baby only God knows my pain. I don’t want to arrive in my house and enter your room My God I’m going to die,” read one gut-wrenching Saturday entry. In another, the dad writes, “My heart is dead my love” and “you were always the reason for my life. I love you my love, my life.”

On Saturday, across the street from where the boy lived in the Bronx, a makeshift memorial had been set up, with pictures of Gioser as well as flowers, candles, balloons and a piece from a foosball table.

“That baby really like foosball,” recalled Aristid Palanco, 37, who said he is Gioser’s cousin.

The boy lived part-time with his mom in Connecticut and part-time with his dad in the Bronx, said the cousin, who added that Morrel lives in the same building as the boy’s dad.

“He a good little kid. His father a good man. He work in construction,” Palanco said.

Palanco said “it’s crazy” if Morrel was behind the deadly ambush.

“That’s family friend, live right here, every day here, eating, whatever. He from here,” Palanco said.

“He fly before, like three weeks before. Some people are not good people. That’s crazy. We like family, everyday here.”

The boy and his father had just flown in from John F. Kennedy International Airport and were en route to a relative’s house when the violence unfolded, Univision reported.

The mourning father told reporters that the thieves knew his family would be the ideal victims.

“It was an attempt to rob me of my belongings without me knowing who it would be because it was my first time coming to Santiago,” Sergio Feliz said.

The suspects passed his family’s car in a white Kia, dad Sergio Luis Feliz Mancebo told Carlos Polanco Noticias, according to a Facebook post.

“They passed us so one would step aside, and we didn’t stop and we kept going and they shot us,” he said, adding he knew his son was hurt because he looked back and saw blood.

Feliz Mancebo told the news service authorities should increase security in the area, according to the post.
