Linda Diane Casey, age 71, of Appleton City, MO, passed away peacefully, surrounded by her loving family at Research Medical Center in Kansas City, MO on January 8, 2026. 

She was born on March 1, 1954 to Gilbert "Gib" and Wilma (Diehl) Jackson in Butler, MO, and spent her early years in Raytown, MO. Linda attended Adrian High School. She lived in several different places around this area, including Belton, Adrian, and Warrensburg, MO, but her favorite place by far was San Diego, CA. She always dreamed of going back and shared many fond memories of her life there. As an adult, she was a hard worker and achieved many of her life goals. Her driven personality helped her excel in her real estate career, as well as insurance sales. She was a member of the Adrian United Methodist Church and attended regularly when she lived in the area.

Linda admired her beloved grandmother, Mary Diehl, and visited her often in Rich Hill, MO. This is where she learned to sew, can, make homemade noodles, and how to be a skilled cook. Linda also adored traveling with and watching with pride as her talented daughter, Mary, competed in numerous dance competitions. Linda enjoyed many trips to the Starlight Theatre, listening to music by Cher, performing in plays, gardening, singing, anything pink, and being surrounded by her family, especially her children, grandchildren, and great-grandchildren, as they were the light of her life. Her gift for gab, authenticity, and quick-witted humor will be missed by everyone who knew her.

Linda was preceded in death by her father, Gilbert "Gib" Jackson; her step-father, Bill "the barber" Gier; her brother, Bruce Jackson; and her grandmother, Mary Diehl. She is survived by her daughter, Jamie Bise, of Adrian, MO; her son, Kelly (Jill) Keister, of Osceola, MO; her youngest daughter, Mary Beth Hill, of Adrian, MO; her mother, Wilma Gier, of Adrian, MO; grandchildren: Samantha McCarty-Keister, of Independence, MO, Tearsten (Coby) Keister, of Warrensburg, MO, Jonhenry (Makenna) Jackson, of Adrian, MO, Tanna (Xander) Keister, of Peculiar, MO, Karter her "Sweet Boy" Keister of Adrian, MO, and Jackson Hill of Adrian, MO; great-grandchildren: Gatlen Wade and Millie Jo; and a host of extended family and friends.

In accordance with her wishes, cremation will take place. A Memorial Visitation will be held on Friday, January 16, 2026, from 5:00 to 7:00 PM at the Atkinson Funeral Home in Adrian, MO. If in attendance, her granddaughters ask that you wear pink in honor of their grandma. In lieu of flowers, Linda would have liked donations given to the Adrian United Methodist Church Youth or your favorite charity.
