A Marine radar intercept officer missing nearly 48 years after he was shot down over Laos during the Vietnam War has been accounted for after his remains were found last year, the Bergen Record reports.

The remains of Marine Corps Reserve 1st Lt. William (Billy) Ryan, of Bogota, N.J., were identified through DNA tests conducted by the Defense Pow/MIA Accounting Agency at the Pentagon, the paper reported Friday.

Ryan’s plane crashed on a combat mission in southern Laos near the Vietnam border on May 11, 1969, the day before his son’s first birthday.

“I always knew my dad died in the crash, and that’s what my mom told me,” Michael Ryan, 48 told the paper. “What she didn’t tell me is that part of her held out hope that maybe she’d see his face again.”

His aircraft was pulling out of a bombing run when it was hit by enemy fire. The pilot bailed out and was rescued.

Ryan was also shot down in 1968 over the Gulf of Tonkin but he survived that crash.

According to the Record, military investigators went to the Laos crash site in 1990 and found his plane seat.

Investigators visited the site on six other occasions from May 2012 to January 2016 to look for remains.

A lab identified the remains as Ryan's and notified Michael last month.

The next day Ryan’s widow Judith was diagnosed with stage-4 stomach cancer.

“I don’t know, it’s strange to me,” Michael told the paper. “We’ve waited 48 years for this. And now I’m looking up at God and saying, ‘Can you give this woman a week to celebrate?’”

Billy Ryan will be laid to rest at Arlington National Cemetery on May 10, the eve of the crash anniversary.
