Reality star Billy Brown died on Sunday night after suffering from a seizure. The 68-year-old was best known for starring in 12 seasons of the docudrama reality series Alaskan Bush People.

“We are so heartbroken to announce that our beloved patriarch Billy Brown passed away last night after suffering from a seizure,” wrote Brown’s son Bear on a private Instagram account. “He was our best friend – a wonderful and loving dad, grandad and husband and he will be dearly missed.”

“He has been part of the Discovery family for years – a trailblazer, a lovely man and most definitely one of a kind. Our heart is with his family and those that knew him and loved him as they deal with this devastating loss,” wrote a statement from the Discovery network.

Alaskan Bush People debuted in 2014, centering on Brown and his family as they lived off the grid in Alaska, isolated from other civilization. In later seasons, the family moved to the North Cascade Mountains in Washington state so Brown’s wife, Ami, could receive medical treatment after being diagnosed with lung cancer. It was announced that she was in remission in 2018.

The 12th season of the show aired in October.
