The specific details surrounding their deaths remain undisclosed.
Born with partially-fused skulls and sharing 30 percent of their brains, Lori and George defied medical expectations from an early age. Despite doctors' predictions that they wouldn't surpass the age of 30, the twins continued to defy the odds, capturing the attention and admiration of people around the world with their resilience and closeness.

Despite being connected to one another throughout their entire lives, the twins had very different personalities and interests.
Lori was an accomplished 10-pin bowler and George, an enthusiastic country and western singer.
George was also transgender, revealing his true identity in an interview with The Sun several years ago.
Despite being assigned female at birth, George always knew deep down that he was a male. "I have known from a very young age that I should have been a boy," George admitted. "I loved playing with trains and hated girly outfits. I kept my desire to change sex hidden - even from Lori - for many years."
Speaking of the difficulty of coming out to his sister, George added: "It was so tough, but I was getting older and I simply didn’t want to live a lie. I knew I had to live my life the way I wanted."
Lori responded to her brother's revelation with unwavering support: "Obviously it was a shock when Dori changed to George, but I am so proud of him. It was a huge decision but we have overcome so much in our lives and together we are such a strong team. Nothing can break that."
Adding another layer to their fascinating lives, Lori shared that she was once engaged but tragically lost her fiancé to a drunk driving accident.
When it came to dating, Lori also shared how George offered her privacy. "When I went on dates, George would bring along books to read and, as we don’t face each other, he could ignore any kissing," she disclosed.
Lori stood at five feet one inch and was fully able-bodied, but George, who stood at four feet and four inches, lived with spina bifida.

During that interview, Lori expressed her desire to have children, saying: "I would love to have myself a family - a husband and children of mine."
Sadly, she was never able to fulfil her dream.
