YouTuber Roman Atwood, best known for his prank videos, is “numb and in complete disbelief” over his mother’s death.

Atwood, 36, shared the tragic news with his Twitter followers, announcing that his mother, Susan Atwood, died while they were on a family vacation.

“As many 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 vitals. No heart rate and her breathing stopped.”

The father of three asked for prayers, “especially for my father” who he says he will by his side through all of this.
