“Sister Wives,” a TLC reality show that has aired for 18 seasons, focuses on Kody Brown, his four wives and their 18 children. He has six children and three grandchildren with Janelle and has said he is estranged from them.

On Tuesday, Kody and Janelle shared the news of Garrison's death via nearly identical messages on their respective Instagram accounts.

“He was a bright spot in the lives of everyone who knew him,” the posts say. “Our loss will leave such a gap in our lives that it will take our breath away.”

TLC said in a statement: “We are devastated to hear of the tragic loss of Garrison Brown. We extend our deepest sympathies and condolences to the Brown family at this difficult time.”

His mother had praised Garrison for his carpentry skills – a family trait – which were evident in the restoration of an old camping trailer and the construction of a custom table he made for her.

The estrangement between Kody and his children from Janelle was a theme in the show's 18th season, which aired last fall.

“We tried to be open and neglect and overlook violations that were thought to have occurred but never did,” Garrison Brown said in one episode.

Police said the death was under investigation.

“At this point there is no evidence of a crime and detectives from the Criminal Investigation Department are investigating,” police said.
