Arlington National Cemetery released the name of the man who died in the cemetery on Friday by an apparently self-inflicted gunshot wound.

Robert Terrill, 92, was a retired Air Force colonel. His wife, Helen Burgess Terrill, died in 2009 and was buried in the section of the cemetery where Terrill was found dead.

The cemetery said that it did not know of any similar deaths at Arlington in the past.

Mike Dickerson, media chief at the Air Force Personnel Center, said that Terrill served in the Air Force for at least 20 years and racked up more than 8,000 flight hours as a command pilot. He attained the rank of colonel in 1959 and retired in 1968.

Terrill lived in Falls Church, according to the cemetery. He and his wife met at Lock Haven University, according to a local news article, and got engaged on Valentine’s Day in 1942. In 2010, Terrill gave the university $250,000 to create a library fund in her honor. He referred to himself at the dedication ceremony as Helen’s “loving soul mate.”
