Theodore and Aspasia Kiapos lived together as a married couple for nearly 64 years, and on Saturday evening, they died together, too.

A devastating house fire in Sun Valley, Calif. killed the sweethearts of six decades.

Neither had a pulse when firefighters were finally able to pull them from the smoldering structure, though both were revived en route to the hospital, The Los Angeles Times reported. However, the reprieve was short lived and both died a little while later at the hospital.

One other person, who has not been identified, was seriously injured by smoke exposure and burns to her hands. A firefighter was also hurt but was later released from medical care.

It took firefighters about 40 minutes to extinguish the flames that killed Theodore, 91, and Aspasia, 90. The husband had worked in a family-owned business, Omega Shoe Polish Co., and his wife was an elementary teacher.

“Ted and Aspasia’s love for one another is a testament to what true love, pure love, and unconditional love is,” the couple’s granddaughter, Sophia Kiapos, wrote on a GoFundMe page. “They passed in body together, but live on in spirit as they dance their way through eternal peace.”
