(CNN) The Dorr family had been waiting for Carl to come home from the Navy for 77 years. This week, he finally did.

About 15 relatives on Wednesday walked onto the tarmac of South Carolina's Greenville-Spartanburg International Airport. They watched as a flag-draped coffin was lowered from the plane into a hearse.

"There was nothing but dead silence," Carl's 70-year-old nephew, Thomas Dorr, who lives in St. Johns, Florida, told CNN. "I knew that what I was experiencing was history."

Carl David Dorr, one of the 429 sailors and Marines killed on board the USS Oklahoma when it was sunk in the Japanese attack on Pearl Harbor, will be laid to rest on Friday -- the attack's anniversary.

Only 35 people on the ship were positively identified and buried in the years immediately following the December 7, 1941, military strike, according to the Defense Department. The unidentified remains were buried as unknowns at the National Memorial Cemetery of the Pacific, which fills the Punchbowl crater in Honolulu.

The Defense Department -- following a push by a Pearl Harbor survivor -- in recent years has been working to exhume those bodies. Using modern advances in technology, it is identifying the remains to give family members the closure and commemoration they have long awaited.

On Wednesday, the Dorr family took three limos and a hearse back to a funeral home in Greenville. Police and the Patriot Guard escorted them, Thomas Dorr said. The processional passed law enforcement and fire officials who offered a salute as they directed traffic.

A fire truck parked on an overpass draped a flag above them.

Once they arrived at the funeral home, the family sent Thomas in first to see Carl's casket. He had studied Pearl Harbor, and he felt like he had a close connection with his uncle because of his love for his grandmother.

Thomas knelt down next to the coffin, put his hand over it and wept, he said. He wept for Carl, who belonged back at home. He wept for Carl's parents, who missed him so much.

"I was crying tears for them," Thomas said.

A child of the Great Depression

Carl was one of six children in the Dorr household, but lost a sibling to rheumatic fever as a child. He worked as a projectionist in a Greenville area movie theater, according to Thomas, and during the Great Depression he supported his family with the money he made there.

While in the Navy, Carl sent his parents back home the cards he received, asking that they put the letters in a chest he built with his father. Carl wanted to keep them and put them in a scrapbook, Thomas Dorr said.

But the 27-year-old fireman second class would not make it home.

In Pearl Harbor, the battleship affectionately known to crew members as "The Okie" capsized about 12 minutes after the first of numerous torpedo strikes. Hundreds were trapped in a dark, watery tomb below her decks, marking the second-greatest loss of life that day.

Carl's family gathered around the radio on December 7, 1941, Thomas Dorr said. They knew Carl's ship had been attacked. They held out hope he survived.

They were told he was missing in action. Then, they learned, he was presumed dead.

After the Defense Department began DNA collection in 2009, his family provided samples in hopes that one day it would help identify Carl's body, his nephew said.

His mother kept an heirloom photograph in her living room "so she could keep an eye on him," Thomas Dorr said. She was able to see her son every day, even if he never made it home at all.

'History repeating itself'

Thomas Dorr knows that photograph well.

He was 20 when he finished boot camp. He visited Mama John's house (his grandmother and Carl's mother), in Greenville, a lean 6 foot 2 and 180 pounds, dressed in a khaki uniform and garrison cap.

Mama John had tears in her eyes, Thomas said, and whispered to him "it's like Carl coming home from war."

She died a year and a half later, Thomas said. But not before he pledged to her that he would honor Carl.

"I made that promise to her that my first-born son would bear his name," Thomas said.

On June 2, 1976, Thomas became father to Carl David Dorr, who grew up to enlist in the Navy right out of high school.

Thomas said it's like "history repeating itself."

The effort to identify the remains

The late Ray Emory knew that hundreds of families across the United States were like the Dorrs -- mourning without being able to lay their loved ones to rest.

Emory, a chief boatswain's mate who manned a .50-caliber machine gun and fired at Japanese aircraft, survived the attack on Pearl Harbor.

During a visit to the National Memorial Cemetery of the Pacific, Emory told CNN in 2012, no one could tell him even where the remains were buried.

So began Emory's journey to get the remains of those lost on USS Oklahoma identified.

Emory's "research efforts" led to the 2003 disinterment of a single casket with the remains of USS Oklahoma crew members from the Punchbowl in 2003, said Lt. Col. Kenneth Hoffman, a spokesman for the Defense POW/MIA Accounting Agency (DPAA).

"And his efforts were key to in 2009, the Department of Defense beginning the collection of DNA family reference samples for all unidentified Oklahoma crew members; a precursor to DPAA commencing a project to identify all 394 individuals," Hoffman said.

Since DPAA disinterred all unknown Oklahoma graves from the Punchbowl in 2015, 189 sailors and marines have been identified and returned to their families, according to Hoffman.

"We are working hard to identify the remainder over the next two years," he said.

The evidence used in the identification process includes historical records, material evidence, skeletal remains, dental material and the comparison of DNA from bones and teeth with family reference samples, Hoffman said.

According to the Defense POW/MIA Accounting Agency, Carl Dorr's remains were exhumed in 2015. And thanks to dental records and DNA, they were finally identified on July 25 of this year.

Laying him to rest

Thomas said he remembered seeing the chest Carl had reserved to hold onto his military correspondence. For 30 years, he looked for it, but no one in the family knew where it was.

Then in 1998, while staying the night at a cousin's house in Georgia, he learned the cousin had been keeping the chest in his garage for Thomas' son, Carl's namesake.

Thomas gave it to his father (Carl's brother) for Father's Day, he said. In the chest were hundreds of letters, USS Oklahoma menus from 1941, Carl's military ID and a picture of the USS Oklahoma that he had turned into a post card. Thomas said his father collapsed over the chest and started wailing.

That year, the family held a memorial service for Carl, with his four living siblings.

All they had of Carl was his belongings in the chest, Thomas said.

"It was a memorial service with the family to accept the fact that we actually were remembering his presence on earth."

But this Friday -- 77 years after he died -- they will have more of Carl than the pictures he took and the letters he wrote. They will bury him close to family members, including his parents.

"It's the end of a story. He lived his life. He died for his country. He's come home. The story ends now," Thomas Dorr said.

He paused. "But he will always be remembered," he said.
