It began as a mystery in the mailbox — a letter originally postmarked in 1967 and labeled “Return To Sender.”

Within hours, it evolved into an emotional tale for one family and a stranger whose lives, they discovered, are intertwined.

Tene Tucker returned to her home outside Atlanta last month after a 10-day vacation and began the usual ritual of sifting through mail that had piled up. It was mostly bills or junk mail. But something else caught her eye.

“I found this letter toward the bottom of the stack, and just looked at it,” Tucker said, “and was like, ‘What is this?’ ”

The small, white envelope had been sent from her address, postmarked Aug. 15, 1967, according to the black stamp at the top of the envelope. “Return To Sender” had been scribbled on the front.

First, Tucker said, she “just kind of stared at it for a while.” After opening the 52-year-old letter, she began putting together the pieces of the puzzle to reunite the letter with the person who penned it.

The letter was written by a woman named Betty Hayes, who mailed it to a man named Marvin Armstead in 1967. Armstead appears to have been stationed at McGuire Air Force Base in Burlington County, N.J.

“Hi son. How are you? I got your letter and was glad to get it,” Hayes wrote, before giving updates on her life. She concluded the letter by writing, “Remember, no one can be more proud of one little boy … From Betty to my son, with love.”

Touched by the letter, Tucker wrote a post about it on social media. She felt an obligation to find Hayes’ family.

“I still was kind of in disbelief that this letter was 52 years old. Just to see the mom kind of reaching out to their son to tell him how proud they were, and talking about the little things,” Tucker said. “It reminds me of my mom when she sends me notes every once in a while.”

A local TV station picked up on Tucker’s post. And less than 24 hours later, a local woman, Mary Hayes, happened to be watching TV with her mother — Betty, the letter-writer herself — when the station’s story about the letter aired.

“It said the address … and then my mom,” said Mary Hayes. “I was very surprised.”

Her brother Sylvester also saw the report. Immediately, he, Mary, and their mom went to Tucker’s house, where they had grown up. Tucker was able to personally hand the letter to Betty, who is now 84 and was the home’s first owner. Betty suffers from Alzheimer’s disease, but appeared to recognize the modest, single-story house, originally built in 1940.

“I’m just excited the letter came back and we were able to read it,” Mary Hayes said. “It was very emotional, it really was.”

UPDATE!!!! Mrs. Betty Hays is still alive and her daughter drove her to the house to retrieve the letter. Such a sweet...

Tucker also learned details about Armstead, the letter’s intended recipient. He is Hayes’ biological nephew, but his mother died when he was 3 years old, so Hayes raised him like her own son. After leaving home at 16 to serve in the Air Force, he worked at Lockheed Martin, received a master’s degree, and was a professor, his family told Tucker.

But Armstead, who is now about 70 years old, also has dementia, and his family has not seen him for about 10 years, Mary Hayes said.

“We’ve been trying to find him,” she said. They think he is still alive and in the Atlanta area, since they believe he sometimes visits local Department of Veterans Affairs hospitals.

Mary Hayes treated Armstead like a brother. They grew up in the home where Tucker now lives. “It was a small house, but we made it,” she said, calling Betty Hayes “a great mom.”

For Tucker, it was a surreal experience to meet the family who grew up in the place she now calls home.

“This house, from the minute I bought it, has just brought so many little blessings,” she said. “I’ve always wondered who was the original owner.”

It’s still a mystery, however, why the letter never got to Armstead, and where it has been for 52 years. It appears that someone put a stamp on the envelope in Phoenix last month, added “Return To Sender,” and put it in the mail.

The Hayes family is “not quite sure how the letter got back here, but they’re really glad that it did,” Tucker said. “If this story made it to Phoenix, Arizona … I would love to find that person.”

The return of the letter has also reinvigorated the search for Armstead. A private investigator who contacted Tucker has agreed to help.

“Wherever Marvin is, he has a good family that loves him and misses him, and they’d love to find him,” she said. “The story doesn’t end here.”
