"It is with our deepest sorrow to report that the Instagram announcement was indeed true," the Bratayleys wrote on YouTube. "In addition to our desire to give the Internet community the chance to begin the grieving process, we also wanted to post this video to show a healthy and happy Caleb doing what he loved. Thank you for all the love and support that everyone has shown our family. And we ask for continued love and support as we move through the grieving process."
In the video, Caleb is seen talking about what he would ask his "future self" if he was given one question.
After a long pause, Caleb jokingly asks, "Is Taco Bell still around?" He later said he would ask if there were "any new sports" in the future.
On Sunday, the family shared a montage video of Caleb's best moments from over their five years of vlogging.
While the family – whose real name is not Bratayley – has maintained that the teen died of "natural causes," the ambiguity of the statement and Caleb's healthy-looking appearance in their last video is causing fans to question the reason for his death. In their videos and social media posts, the Bratayleys have asked for privacy while the grieve and have not gone into specifics about Caleb's death.
It's unclear if the Bratayleys will continue vlogging following Caleb's death.
