'Sister Wives' star Janelle Brown 'brought to tears' from donations after son Garrison's death

"Sister Wives" star Janelle Brown is touched by the outpouring of donations to a shelter in honor of her late son Garrison, who died at 25 last week.

The reality star said she was "brought to tears" when she learned that people were making donations to animal shelters to honor her late son.

"I'm being told about everyone's donations to @highcountryhumane @arkcatsancutary in Garrison's name," she captioned two photos of Garrison with his cats on Instagram. "Thank you for all your generosity. It means so much. The cats he adopted from both agencies were so important to him. He loved being a cat dad."

She shared screenshots showing the websites of the shelters where he adopted his cats: High Country Humane in Flagstaff, Arizona, and Ark Cat Sanctuary in Parks, Arizona.

The late son of Janelle and Kody Brown, Garrison Brown first appeared on the first season of the TLC reality television program in 2010, which has followed one of America's most famous polygamous families over 18 seasons.

Flagstaff Police Department spokesperson Sgt. Jerry L. Rintala confirmed Garrison Brown's death in an emailed statement to USA TODAY last 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 remembered as 'bright spot' by parents, 'Sister Wives' stars

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.

"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 March 5. "We ask that you please respect our privacy and join us in honoring his memory." Meri Brown shared similar sentiments on Instagram.

In a follow-up post on Friday, Janelle Brown wrote: "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.

Fellow stars Christine and Meri, who have both left their respective marriages with Kody Brown, 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.
