The YouTube community has lost one of its own. Caleb Logan, one of the stars of the popular YouTube family-vlogging channel Bratayley, has died. The family and the channel’s media company, Maker Studios, have confirmed the 13-year-old’s passing.

“Yesterday at 7:08 p.m. Caleb Logan Bratayley passed away of natural causes,” his parents, Katie and Billy, wrote on Instagram Friday. The post was accompanied by a shot of Caleb and his 7-year-old sister, Hayley. “This has come as a shock to all of us,” the caption continues. “Words cannot describe how much we will miss him.”

Maker Studios commented on his death Friday, saying they were “heartbroken” over the loss. 

The Bratayley family shared a video update with their fans Saturday. In the description of the video “Dear Future Self” the brood explains that they decided to share new footage of Caleb, shot one day prior to his death, in order to better help their fans grieve.

“It is with our deepest sorrow to report that the Instagram announcement was indeed true,” the family wrote. “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.”

Since Caleb’s passing, other members of the YouTube family-vlogging community have publicly mourned the Web star.

“I didn’t believe it. I thought, oh, I thought their Instagram was hacked ... I hope it’s not true and my management confirmed it,” Daily Bumps channel vlogger Bryan Lanning said in his video “Life is Fragile” Saturday. “I can’t imagine what their going through.”

Maker Studios co-founder and fellow YouTubers Shay Carl Butler and his wife, Colette Butler, have also commented on the tragedy. 

Fellow family-vlogging channel Kitties Mama said they’re “saddened and shocked” by Caleb’s death. “He was a super sweet and funny boy and he will be missed by many,” the family wrote on Instagram Friday. “We imagine there is no pain more far-reaching and deeper than losing a child. Our hearts and prayers go out to the Bratayley family as this most difficult time.”

Bratayley launched on YouTube in December 2010. The channel also stars Annie, a 10-year-old gymnast. At present, the channel has over 1.5 million subscribers. Caleb’s own YouTube channel, blazeNoutlaws, has just over 108,000 subscribers.

The Bratayley family has asked for their supporters continued love and support as they grieve.
