Caleb Logan Bratayley died on September 29 at his family's house in Maryland, USA at age 13
The youngest Youtube star, Caleb Logan Bratayley is dead.
The 13-year-old star is reported to have died under mysterious circumstances and TMZ reports that the only explanation so far is he suffered a "medical emergency" even though he seemed fine an hour ago.
Caleb - whose family has gained more than a billion YouTube views - died on Thursday night (September 29) in Maryland. Law enforcement say a 911 call was placed at 7 PM, and police and fire responded to his family's home. Caleb was later rushed to hospital where he was declared dead.
The family announced the same day that he "passed away due to natural causes." However, authorities have ruled out suicide as cause of death because there were no drugs, and there is no history of drug use. The 911 call was for a "medial emergency."
Reports say the coroner will conduct an autopsy as part of its investigation.
