The devastated father of a young Bronx man recalled the heart-wrenching moments he discovered his son had been shot by his cousin, who pulled the trigger of a gun he thought was unloaded.

“Mohammed came out, ‘Daddy, daddy,’ and then he fell by the computer desk,” distraught dad, Sekou Touray, recalled Wednesday through tears, as he stood in front of the Concourse Village apartment building where tragedy struck the day before.

Touray’s 18-year-old son, Mohammed, was fatally struck by a bullet after handing a gun to his cousin, who thought it was empty.

“I knew he wasn’t going to make it,” the 60-year-old father of five added. “It hit him right in the heart — not the chest, but the heart.”

Mohammed had removed the ammo magazine from his pistol before passing it to 21-year-old Omar Turay, around 2:45 p.m. Tuesday inside the younger cousin’s bedroom.

But Touray had racked the slide of the gun before taking the ammo out — securing a bullet into the chamber and effectively rendering the gun ready to be fired.

Thinking the gun was unloaded, Turay accidentally fired the weapon, striking his younger cousin once in the chest, cops said.

Sekou, from Liberia, said he first heard an initial “pop” which he described as sounding like a gun being fired, just minutes earlier. When he went to check on it, the pair told him, “something dropped.”

When they heard a “second pop” moments later and realized Mohammed had been struck.

“I thought he did it to himself,” Sekou said. “When I asked what happened, he said he was looking at the gun and then it went off. I didn’t even know there was a gun, so I asked if this was even real so we can call 911.”

Mohammed, a high school senior, was rushed to Lincoln Medical Center, but he could not be saved.

Turay was charged with manslaughter and criminal possession of a weapon and was awaiting arraignment in Bronx court on Wednesday.

“That’s his cousin. He loves this boy. These boys love each other,” the distraught father said.
