YouTuber Roman Atwood is mourning the loss of his mother, Susan Anne Christman.

The vlogger, who announced her passing on Twitter, said she died in a freak scooter accident while they were on a family vacation.

"As most of you know my family and I are on vacation together," he wrote. "Yesterday my mom was riding around with my nephew on some little scooters. She fell off hers and hit her head.

"She immediately lost all vitals," he continued. "No heart rate and her breathing stopped."

"I've never been more in shock in my life," he wrote. "I'm numb and in complete disbelief. My heart is so heavy. We are all broken over here.

"Mom was everything to us."
