The body pulled from the East River over a week ago has been identified as a 21-year-old University of Albany student who disappeared earlier this month, police said Monday.

John Carlos Garcia-Mendez, 21, of Washington Heights, had been reported missing May 7. He was last seen on Myrtle Avenue in Albany, the Albany Police Department said.

The NYPD confirmed on Monday that the body found floating off Dumbo, Brooklyn, between Adams and Johns streets at 8:15 a.m. on May 19 was the missing physics student.

There were no signs of trauma on Garcia-Mendez’s body, and his death was not considered suspicious, police said.

His family was informed Friday.

“My heart is broken,” his mother, Gloriza Mendez, 55, told The Post from her Washington Heights apartment.

“He was my only child. I don’t know how to survive without him.”

The distraught mother said she hadn’t seen her “nice and quiet” son since Christmas break, but that they spoke often on the phone.

They had a brief conversation May 6, the day before he vanished, she said.

“I had a bad feeling,” she recalled. “l asked him ‘what’s going on?’ He didn’t say anything.”

Garcia-Mendez was supposed to graduate this month, but had recently been worried about not finishing up his coursework in time, after switching majors from art to physics, his mother said.

“He was not doing good in school,” she said. “I think he was depressed about not graduating.”

After not hearing from her son for two days, Mendez said she went to his apartment in Albany. There, she found his house keys and his computer.

“He was a good kid. He was not a street kid,” she said. “I just want justice for my son. If anyone knows anything, please go to the police and tell them.”

Kristina Alejos, a classmate, remembered Garcia-Mendez in a Facebook post as a “sweet and respectful individual who always made us smile.”

Gianna Jimenez, a friend who said she had been his neighbor since she was 4, began a GoFundMe campaign for funeral expenses.

“The news of him going missing had pained me and I wanted to believe the best,” she wrote. “I wanted to believe he just lost his way and he would find his way back home, but God had other plans.”

The campaign had raised more than $2,300 by Monday evening.

The University of Albany also paid tribute to Garcia-Mendez, calling his death is “heartbreaking” and saying it would be felt by the entire college community.

“We offer our deepest condolences to his family and friends,” the SUNY college said in a statement.

The funeral is scheduled for Wednesday.
