On Tuesday, friends and strangers in the community attended the internment for Edward K. Pearson, 80, of Naples, Florida, at Sarasota National Cemetery.
They carried U.S. flags. Some laid flowers. Others reached out to touch the veteran's urn.
"It shows that Americans still care," mourner Donald Johnson said of the turnout. "We still have a special empathy for mankind."
Pearson had no immediate family and died Aug. 31, according to ABC News affiliate WFTS-TV in Tampa Bay
His obituary went viral on social media after the funeral home said in a service announcement that he had no immediate family and that the public was welcome to attend, The Associated Press said.
Pearson served from 1962-1964 and was honorably discharged, the Legacy Options Funeral and Cremation Services said. He was born in Ridley Park, Pennsylvania, according to WFTS-TV, and had lived in Naples for the last 25 years.
One by one at Tuesday's service, mourners stepped up to the podium to thank Pearson for his service and thank those who had gathered to remember him.
"First off, I really want to show my profound gratitude and appreciation for each and every one of you coming out here to show this veteran the dignity, honor and respect that he justly deserves. When I first heard about him on the news, that he had no family, well that broke my heart. And that he was going to be laid to rest with nobody around. To me, that's not right. No veteran, man or woman, should ever have to have that happen to them ... But when the call went out over social media and the news, look what happened ... Just look around. This is a sure show of true humankind and compassion," said one mourner named Bob.
The service was held at 12:30 p.m. and he was interred with full military honors. After the honor guard folded the U.S. flag, it was put on display at the funeral home.
