In Loving Memory of Katy Dian Johnson  October 17, 1970 – May 6, 2025

Katy Dian Johnson passed away on May 6, 2025, at the age of 54. She was strong-willed, fiercely independent, and one of the most genuine souls this world has ever known.

Katy was beautiful inside and out, with a deep empathy for all—people and animals alike. She gave advice rooted in love and wasn’t afraid to tell you like it was. She was a fighter—tirelessly facing her own battles while always showing up to help you with yours.

To most, she might’ve seemed like a woman of few words. But those lucky enough to know her, knew she had plenty to say, especially when it mattered most or when she needed a well earned rant. Her sense of humor was dry, sharp, and probably inappropriate to some—especially when someone took a tumble (as long as they were okay, of course). Katy’s love was steady, loyal, and fierce. If she was in your corner, you knew it. And if you gave her a reason not to be, well, you knew that too.

Katy didn’t love attention, so this obituary is already pushing it. But she deserves to be remembered loudly. For her strength. Her humor. Her compassion. Her fight.

She is survived by her daughter, Riley Johnson, who proudly inherited her fierce stubbornness and independence; her dog Maggie, who never left her side; her sister and soulmate, Diana Mathews; her brother Tony Bounds, of whom she was so proud of; her nieces and nephew—McKinley and Andrew Mathews, and Ashley Kennedy—who brought her so much joy; her husband, Wilhelm Detillier, who stood faithfully by her side through it all; and many other loved ones who were lucky to be part of her life.

Katy was one of a kind. She was an amazing wife, sister, friend, and mother. She will, forever and always, be deeply missed and fiercely remembered.
