Jeffrey Scott O'Brien

Jeffrey Scott O’Brien, 65, was born February 10, 1961, in Austin, Minnesota, and passed away peacefully in his sleep on September 12, 2026, in Casper, Wyoming, with the comfort and care of hospice.

Jeff enjoyed the simple pleasures of life. He loved being outdoors, especially hunting, fishing, camping, and trap shooting. He also enjoyed playing pool and settling in to watch classic television shows such as MASH* and Bonanza. He was a true steak-and-potatoes kind of guy and knew what he liked.

Jeff is survived by his three children, Jeremy O’Brien of Casper, Wyoming; Kristen (Victor) Nunez of Casper, Wyoming; and Whitney (Arturo) Camacho of Akron, Colorado.

His grandchildren are Chase, Brandon, Kimberly, Jesse, Candy, Trystan, Allisyn, and Carson.

He was also blessed with four great-grandchildren: Kieffer, Chloe, Oliver, and Seriphina.

Jeff is also survived by his siblings, Mike (Melody) O’Brien of Many, Louisiana; John (Carol) O’Brien of Lake Mills, Wisconsin; and Cathleen O’Brien of Marshfield, Wisconsin, as well as numerous nieces and nephews.

He was preceded in death by his parents, Caroline “Carrie” Walters and Francis “Dick” O’Brien.

He leaves behind family and memories that will remain part of his story.
