The Surpassing"Sister Wives" are remembering Janelle and Kody Brown's son Garrison, who died at 25 this week.

In separate Instagram posts, fellow stars Christine and Meri paid tribute to their stepson with heartfelt messages.

"Garrison was a wonderful, caring brother who understood Truely’s need for a hobby and built her a flowerbed. We’ll miss him forever," Christine Brown wrote in a clip that showed the late reality star building a planter with his sister Truely.

"Our family is deeply saddened to announce the loss of our beautiful boy, Robert Garrison Brown. He was a bright spot in the lives of all who knew him. This loss will leave such a big hole in our lives, and it takes our breath away," Meri Brown wrote in her Instagram caption.

"We ask that you please respect our privacy during this time and join us in honoring his memory. Garrison, you are loved and will be missed," she added.

Janelle Brown, Garrison's mom, posted a follow-up to her original Instagram post on Friday, writing, "I had all my children together last Christmas. It was amazing as it's hard with everyone's busy lives to coordinate time like this. I am extremely grateful now that we had pictures taken" surrounded by the family's children.

Flagstaff Police Department spokesperson Sgt. Jerry L. Rintala confirmed Garrison Brown's death in an emailed statement to USA TODAY earlier this week.

Police officers responded to a report of a death inside a home and discovered Garrison Brown had died as a result of an apparent self-inflicted gunshot wound. Rintala added that there is no indication of foul play in Garrison's death. Detectives from the department's Criminal Investigations Division are investigating the case.

In a statement issued to USA TODAY, a rep for TLC added the network was "devastated to hear of the tragic loss of Garrison Brown" and extended "heartfelt condolences to the Brown family at this difficult time."

Garrison Brown first appeared on the first season of the TLC reality television program in 2010, which follows one of America's most famous polygamous families.

Janelle and Kody Brown previously remembered their son in a pair of their own Instagram posts.

"Kody and I are deeply saddened to announce the loss of our beautiful boy Robert Garrison Brown. He was a bright spot in the lives of all who knew him. His loss will leave such a big hole in our lives that it takes our breath away," Janelle Brown said on Instagram. "We ask that you please respect our privacy and join us in honoring his memory."

Garrison Brown was one of Janelle and Kody Brown's six children, in addition to Logan, 29; Madison, 28; Hunter, 27; Gabriel, 22; and Savanah, 19. Christine and Meri Brown have both left their respective marriages with Kody Brown in recent years.

In 2021, Christine announced the split on Instagram and one year later, Meri Brown (Kody Brown's first wife, whom he married in 1990) revealed their breakup in an episode of "Sister Wives: One-on-One."

"After more than a decade of working on our relationship in our own unique ways, we have made the decision to permanently terminate our marriage relationship," Meri and Kody Brown said in a statement on Instagram.
