Caleb Logan Bratayley's mother has revealed a few more details surrounding the 13-year-old YouTube star's sudden death.

Originally, Caleb's mother Katie posted an instagram message stating Caleb died last Thursday of "natural causes." On Monday, she provided a bit more explanation.

"Caleb's death has raised many questions about how and why this could happen to a seemingly healthy boy," Katie wrote on Instagram. "Sadly, tests have confirmed today that Caleb passed away from an undetected medical condition. We'll have more definitive answers in the coming weeks but ask that you help us celebrate his life instead of focus on his death."
