Mia Rose Mercedes Lopez, 10, beloved daughter of Marissa Lopez of Rock Island, Illinois, passed away Thursday, October 8, 2026, at University of Iowa Health Care in Iowa City, leaving behind a world made brighter by her beautiful spirit.

In April 2026, Mia was found to have a brain tumor and was later diagnosed with a rare form of brain cancer called CIC-DUX4 sarcoma, beginning a six-month journey filled with challenges no child should ever have to face. Throughout her treatment, she showed incredible courage, strength, and determination. Even on the hardest days, Mia never lost the spark that made her so special, continuing to bring smiles and laughter to those around her.

Mia had a larger-than-life personality, a wonderful sense of humor, and a quick wit that could make anyone laugh. She had a special way of bringing happiness to those around her and making even the hardest days a little brighter. She loved dancing, gymnastics, and music, especially her favorite girl group, KATSEYE, and was proud to be one of their biggest “EYEKONS.” Mia was a fifth-grade student at Rock Island Center for Math & Science, where she enjoyed spending time with her friends and, like most kids her age, considered recess and lunch the best parts of the school day!

Her family and friends held a special place in her heart, and nothing made her happier than being with the people she loved most. The bond she shared with her mom, Marissa, was truly extraordinary, and the two shared an inseparable connection filled with unconditional love, laughter, and countless beautiful memories.

Although Mia’s time on earth was far too short, the impact she made will last a lifetime. She filled the lives of those around her with love, laughter, and unforgettable memories. Her joy was contagious, her spirit was beautiful, and her ability to make others smile was truly a gift. Mia was deeply loved, endlessly cherished, and will be missed more than words could ever express.

Those left to cherish Mia’s memory include her mother, Marissa, and her half-sister, Avianna Wermuth-Gulley, along with countless family members and friends who loved her dearly.

Visitation is 4:00 to 7:00 p.m. Wednesday, October 28, in the Horizon Room at Trimble Funeral Home at Trimble Pointe, 701 12th Street, Moline. Funeral services are 10:30 a.m. Thursday, October 29, at the funeral home, with The Rev. Damon T. Colvin officiating. In keeping with Mia’s bright and joyful spirit, her family invites friends to wear bright colors, especially her favorites, green and pink, rather than black.

Burial will follow services at Rock Island Memorial Park. Memorials may be made to the family.
