A missing Long Island war vet whose bones were found buried in a basement with the help of a psychic was laid to rest at a funeral Friday.

George Carroll — an army corporal in the Korean War, who vanished in 1961 — was mourned at Calverton National Cemetery in Riverhead after his skeletal remains were unearthed last Halloween.

“It all came rushing back — all the things we missed out on and everything he missed,” Carroll’s son, Steve, 62, told The Post. “It was like he died last year, we all had to go through the grieving process again.”

He added that dear dad would have wanted a proper goodbye. “My father so deserved this; he had an untimely death.”

Carroll’s skeletal remains were discovered under his former Lake Grove home by his sons, who had been tipped off by a psychic.

Spurred by the clairvoyant, who purportedly got a hit on the basement, his son Mike Carroll bought the home from his now-deceased mother in 1998 and spent years digging around.

The psychic predicted that his father had died from blunt force trauma — a fact that investigators later confirmed, saying his skull had been cracked open. His death was later probed as a homicide.

But on Friday, relatives said the mystery of Carroll’s death may never be solved.

“Nobody will every know what really happened,” his daughter Jean Kennedy, 65, said after the ceremony.

She added, “We’ve had the gift of finding our father before we leave the earth. I prayed to the Lord everyday to answer my prayer on where he could be.”

She added, “I’m happy that it’s over. It’s another chapter in our lives.”

More than 50 mourners — tearful family members among them — said their final goodbyes at the ceremony, which included a bag pipe rendition of “Amazing Grace.”

A pal and fellow Korean War vet passed around a never-before-seen photo of Carroll riding in a military vehicle with actress Marilyn Monroe. And members of an honor guard presented his family with an American flag.

Carroll’s remains were cremated and placed in a small wooden box, which his family plans to store in a Columbarium.

It wasn’t immediately clear Friday if investigators were still probing his death as a homicide.
