William “Bill” Edward Costill, 92, of Lake Havasu City, Arizona, passed
away peacefully in his home, surrounded by family on September 24, 2025.

William Edward Costill was born on July 18, 1933, to William D. Costill
and Lillian Poteet (Costill), in Los Angeles, California. He remained
on Los Angeles during much of his younger years.

Bill graduated from Montebello High School and soon after, with skates
in tow, enlisted in the United States Navy. Though his dream was to
serve on submarines, his height kept him from that path, and he proudly
served four years of ship duty instead. Following his military service,
he worked as an electrician with Union Pacific Railroad before beginning
a long career with Smart & Final, where he worked for more than 30 years
before retiring.

Bill had many hobbies throughout his life. In his younger years he
enjoyed building model trains, go-karts, and slot cars. His greatest
love was always roller skating which he continued doing until he
retired. In life his passions were going to Speedway, cheering on his
beloved Arizona Diamondbacks and favorite NASCAR drivers.

On March 2, 1968, Bill married the love of his life, Carolyn. From that
day forward, he embraced his role as a devoted husband and father.
Together, they raised three daughters and made countless memories on
annual family trips across the United States and Canada. Bill was known
for his cheeky since humor, fun spirit, and willingness to say “yes” to
life’s adventures.

He was preceded in death by his father, William D. Costill, mother
Lillian D. Poteet, brother Jerry T. Costill, and beloved daughter, Cheri
Lynn Ortega.

He leaves to cherish his memory: his wife and love of more than 60
years, Carolyn Costill; daughters Terri Walter and Tina Dunlap; 11
grandchildren; and 15 great-grandchildren; and a host of other relatives
and friends.

Bill's legacy is one of love, laughter, and family — a life well lived
and deeply cherished.
